SQL Primary Key

A question is always there when you face an Interview related to Software Developer, Web developer or any profile related Database and Web or Mobile applications. This Section Help you in answering Database Interview Questions, MySQL Interview Questions and Primary Key Interview Questions.

What is a Primary Key?

So answers is :

A Primary keys provide a unique Identification for every record in a database table.  

A table can have only one primary key, which could be either a single column or made up of multiple columns. 

A SQL Primary key could be a single column or set of few columns to create a unique combination. 

When multiple columns are used as a primary key, it is known as a composite primary key.

A Primary Key column cannot have NULL values.

A Primary Key is always unique.

The SQL PRIMARY KEY is also known as Primary Key Constraint.

What are the main features of SQL Primary Key?

  • SQL Primary key implements the integrity in the database table.
  • SQL Primary key is the lifeline of the Relational Database. 
  • SQL Primary key always has unique data.
  • Maximum length of a SQL Primary Key could be 900 bytes.
  • The SQL Primary key can combined maximum of 16 columns at a time

How to create a Primary Key or How to Define a Primary Key Constraint?

1#Create a Primary Key while Creating a New Table

We can define a Primary Key Constraint while creating a Table. 

The syntax for creating a table with Primary key is as follow:


    ID int NOT NULL,

    FirstName varchar(255) NOT NULL,

    LastName varchar(255),

    EmailID varchar(100),



2# Using Alter Table 

If Primary Key is not created at the time of Table creation we define Primary Key Using ALTER Command in SQL.

Syntax to create a Primary Key using Alter Command is :


How to Delete or Drop a Primary Key?

Once a SQL Primary Key is created we can drop it or delete it if required. Here is the SQL command of Dropping a Primary Key:

LinkedIn jQuery Assessment

Here we have given the collection of jQuery Questions and Answers asked in Linked in assessment. LinkedIn Assessment is a test of particular skill. After passing this skill you will get a Bade in your profile and that you can share with your network.

What’s the difference between these two snippets?

$('button').on('click', function(){ alert('you clicked the button!'); });
$('button').click(function(){ alert('you clicked the button!'); });
  • Only the second one will work; jQuery does not have a function called .on.
  • The second snippet will not function.
  • Nothing .click(function) is shorter way to write .on('click', function).
  • The first snippet will execute for every button on the page, the second will only apply to the first button.

What does the following line of code do?


  • Loads a paragraph tag from a remote server using AJAX
  • Aliases jQuery to a variable p
  • Selects all paragraphs on the page
  • Creates a new paragraph tag and inserts it into the body tag

Given the following HTML, how could we use one line to hide or show the button?

<button class="btn btn-primary" type="submit">Continue to checkout</button>
  • $('.btn-primary').toggle();
  • $('.btn-primary').showHide();
  • $('.btn-primary').not(':visible').show();
  • $('.btn-primary').css({ display: 'block'});

Working with AJAX, we may run into situations where a piece of code should not be run until after multiple AJAX calls have completed successfully. Say we need to call two external services for JSON data (a list of students, and a list of classes). And only after retrieving those data will we perform some manipulations on a page. What is the preferred way for dealing with this scenario?

  • [ ]
$.get([ '', '' ], function(studentRequest, classRequest) { 
  // the rest of the code goes here 
  • [ ]
$.when( $.get(''), $.get('') ).done(function(studentRequest, classRequest) { 
  // the rest of the code goes here 
  • [ ]
$.bind( $.get(''), $.get('') ).done(function(studentRequest, classRequest) { 
  // the rest of the code goes here 
  • [x]
$.ajax('', { success: function(studentRequest) { $.ajax('', { success: function(classRequest) { 
  // the rest of the code goes here 
} }); } });

Given the snippet of HTML below, what is the difference between the two lines that follow it?

    <li>Item 1</li>
    <li>Item 2</li>
    <li>Item 3</li>
    <li>Item 4</li>
  • .get() retrieves a DOM element, and can’t be chained, eq() retrieves a jQuery object, and can be chained.
  • .get() retrieves a jQuery object, and can’t be chained, eq() retrieves a DOM element, and can be chained.
  • .get() retrieves a jQuery object, and is zero-indexed, eq() retrieves a DOM element, and is 1-indexed.
  • .get() retrieves a DOM element, and is zero-indexed, eq() retrieves a jQuery object, and is 1-indexed.

Suppose we want to have a ball created from an HTML element (id=ball) move down and to the right from its original location when clicked, and move back into its original place when finished. Given a starting point of this, which of these snippets would accomplish that goal?

$('#ball').click(function() {
  // Our code goes here
  • [x]
$(this).animate({ top: '+=100', left: '+=100', }, { duration: 600, complete: function() { $(this).animate({ top: '-=100', left: '-=100', }, 600) } });
  • [ ]
$(this).animate({ top: '-=100', left: '-=100', }, 600, function() { $(this).animate({ top: '+=100', left: '+=100', }, 600) });
  • [ ]
$(this).animate({ top: '=100', left: '=100', }, { duration: 600, complete: function() { $(this).animate({ top: 0, left: 0, }, 600) } });
  • [ ]
$(this).animate({ top: '100', left: '100', }, 600, function() { $(this).animate({ top: 0, left: 0, }, 600) });

Given the following CSS and HTML codes below, how could you apply the success class to the feedback div?

.success {
  color: green;
  background: #ddffdd;
<div class="feedback">
  Thank you for answering this survey.
  • $('.feedback').hasClass('.success');
  • $.css('.feedback', '.success');
  • $('.feedback').addClass('success');
  • $('.feedback').css('.success');

Below is an example page snippet that includes a couple of messages in a list, and a code snippet that retrieves a few hundred messages from a API endpoints using AJAX. How might we add these items to the page snippet in a way that avoids performance problems with DOM insertions?

<div class="message-area">
  <ul class="message-area--list">
    <li>Existing message 1</li>
    <li>Existing message 2</li>
.done(function(data) {
  var tonsOfItems = data.messages;
  // add all these messages to a large page
  • { $('.message-area--list').append('<li>'+item+'</li>'); });
  • var tonsOfListItems = { return '<li>'+item+'</li>'; }); $('.message-area--list').append(tonsOfListItems.join(''));
  • Removing the event handlers with JavaScript will be slower than removing them $.each(tonsOfItems, function(idx, item) { $('<li>'+item+'</li>').appendTo($messageList); });
  • $.each(tonsOfItems, function(idx, item) { $('.message-area--list').append('<li>'+item+'</li>'); });

What is jQuery?

  • jQuery is a bridge between Java and Javascript that makes native apps easier to write.
  • jQuery is a plugin for JavaScript that makes database queries easier to write.
  • jQuery is a collection of JavaScript functions that makes finding and manipulating elements on a page, AJAX, and other things easier.
  • jQuery is a Chrome extension that allows users to create their own extensions with just a few lines of JavaScript.

We want to create a new jQuery plugin called linkUpdater that can be chained onto other jQuery selector like a normal plugin. It should update all the links in the referenced collection so they open in new windows or tabs. Below is the first cut. What is one problem with this plugin?

"user strict";
($.linkUpdater = function() {
  this.find('a').attr('target', '_blank');
})( jQuery );
  • this needs to be wrapped, like $(this), in order to be chained in a plugin.
  • jQuery plugins can’t be safely authored in strict mode.
  • In order to be used by other code, plugins need to be added to the global namespace, not wrapped in a function expression.
  • Our plugin should extend jQuery.fn, not jQuery itself.

Generally speaking, when used on a web page, how should jQuery be installed, and why?

  • Just before the closing body tag, because we want to avoid blocking other resources from loading, and we use the ready method to make sure our code fires after the DOM is ready
  • Using the highest version number possible because only jQuery 3 and up are compatible with Internet Explorer 7
  • In the head tag because we want jQuery available as soon as possible
  • From a CDN because we want to be able to use jQuery online or offline

Given the following HTML, how could we make this button disappear from the page using jQuery?

<button class="btn btn-primary" type="submit">Continue to checkout</button>
  • $('.btn-primary').hide();
  • $('.btn-primary:visible').not();
  • $('.btn-primary').visibility(false);
  • $('.btn-primary').show(false);

What is the difference between $('header').html() and $('header').text()?

  • $('header').html() returns the inner HTML of the header. $('header').text() returns only the text
  • $('header').html() returns only the HTML tags used, without the text. $('header').text() returns only the text
  • $('header').html() strips all HTML from the header. $('header').text() always returns an empty string.
  • $('header').html() returns all headers in an HTML document. $('header').text() the first line of a text file.

When writing jQuery plugins, we often provide default options that may be overridden by the end user. What jQuery function is most useful for this purpose?

  • $.extend
  • $.clone
  • $.fn.extend
  • $.merge

There are times when you might want to programmatically trigger an event, instead of simply reacting to user input directly. Given this markup, Which choice will NOT cause a click event to the select box when the button is clicked?

    Here's a button you can click: <button class="btn">Click Me</button>
      Further down the page, there's a select box.
      <option value="1">One</option>
      <option value="2">One</option>
      <option value="3">One</option>
      <option value="4">One</option>
  • $('button').on('click.myApp', (function() { $('input[type=select]').trigger('click'); });
  • $('button').on('click', (function() { $('input[type=select]').click()); });
  • $('button').trigger(function() { $('input[type=select]').click(); });
  • $('button').click(function() { $('input[type=select]').click(); });

You have an absolutely positioned element inside a relatively positioned parent element, and you want to animate that element within its parent element. What jQuery function is most useful for finding the initial coordinates of the .animate-me?

  .parent {
    position: relative;
    top: 3em;
    width: 50%;
    min-height: 50vh;
    margin: 0 auto;

  .animate-me {
    position: absolute;
    top: 40px;
    right: 30px;

<div class="parent">
  <div class="animate-me">
    This box will move!
  • $('.animate-me').offset();
  • $('.animate-me').each();
  • $('.animate-me').position();
  • $('.animate-me').offsetParent();

You want to work with AJAX using a Promise-like interface instead of nested callback functions. What jQuery API should you use?

  • jQuery.sub
  • jQuery.ajaxTransport
  • jQuery.Deferred
  • jQuery.proxy

What is tricky about jQuery’s nth- filters (:nth-child, :nth-of-type, etc.) relative to other filters?

  • Referring to lists of items, they are 1-indexed (like CSS), not 0-indexed (like JavaScript).
  • They don’t return the jQuery object, and cannot be chained.
  • They can return the wrong items if the DOM was recently manipulated.
  • They are not part of CSS, so they don’t get the performance benefits of passing through the document.querySelectorAll.

jQuery’s AJAX functions return objects that implement the Promise API. As a result, you can chain promises and avoid nested callbacks. What does that look like?

  • [x]
  .then(function(response) {
    // Data from first GET is here as 'response'
    return $.get('');
  .then(function(response) {
    // Data from second GET is here as 'response'
  • [ ]
  .catch(function(response) {
    // Data from first GET is here as 'response'
    return $.get('');
  .done(function(response) {
    // Data from second GET is here as 'response'
  • [ ]
$.get('h', function(response1) {
  // Data from first GET is here as 'response1'

  $.get('', function(response2) {
  // Data from second GET is here as 'response2'
  • [ ]
  .then(function(response) {
    // Data from first GET is here as 'response'
    return response;
  .get('', function(response) {
    // Data from second GET is here as 'response'

You want to have a ball that is created from an HTML element (id=ball) move down and to the right of its original location when clicked, and move back to its original place when finished. What snippet, added to the code below, would do this?

$('#ball').click(function() {
  // Our code goes here
  • [ ]
  top: '-=100',
  left: '-=100',
}, 600, function() {
  top: '+=100',
  left: '+=100',
  }, 600)
  • [x]
  top: '+=100',
  left: '+=100',
}, {
  duration: 600,
  complete: function() {
  top: '-=100',
  left: '-=100',
  }, 600)
  • [ ]
  top: 100,
  left: 100,
}, 600, function() {
  top: 0,
  left: 0,
  }, 600)
  • [ ]
  top: 100,
  left: 100,
}, {
  duration: 600,
  complete: function() {
  top: 0,
  left: 0,
  }, 600)

The way .wrap() works is sometimes misunderstood. Given the DOM and jQuery snippets below, what does the modified DOM snippet look like?

<div id="container">
  <div class="item">Here's an item</div>
$('#container').wrap('<div class="wrapper"></div>').css('border', '2px solid red');
  • [ ]
<div class="wrapper" style="border: 2px solid red;">
  <div id="container">
    <div class="item">Here's an item</div>
  • [x]
<div class="wrapper">
  <div id="container" style="border: 2px solid red;">
    <div class="item">Here's an item</div>
  • [ ]
<div id="container" style="border: 2px solid red;">
  <div class="wrapper">
    <div class="item">Here's an item</div>
  • [ ]
<div id="container">
  <div class="wrapper" style="border: 2px solid red;">
    <div class="item">Here's an item</div>

How can you select the following blockquote AND the list in a single call to jQuery() without chaining?

<div class="quotes">
  <blockquote data-favorite="false">A quote</blockquote>
  <blockquote data-favorite="true">A favorite quote</blockquote>
  <blockquote data-favorite="false">A quote</blockquote>
  <blockquote data-favorite="false">A quote</blockquote>

<ul class="menu-first">
  <li>Item 1</li>
  <li>Item 2</li>
  <li>Item 3</li>
  <li>Item 4</li>
  • $('.quotes + .menu-first')
  • $('.quotes .menu-first')
  • $('.quotes, .menu-first')
  • $('.quotes' + '.menu-first')

Effects like show, hide, fadIn, and fadeOut can be called with no arguments, but can also take arguments for how long they should last. Which is NOT a duration argument supported by these functions?

  • “fast”
  • “extreme”
  • 2000
  • “slow”

Though jQuery offers visual effects, it is considered a best practice to use CSS to set up different states triggered by classes, where it makes sense. What’s the easiest way to enable and disable a class bounce on an element with the ID dialog?

  • $('#dialog').classToggle('bounce')
  • $('#dialog.bounce').removeClass().addClass()
  • $('#dialog').addOrRemoveClass('bounce')
  • $('#dialog').toggleClass('bounce')

What is the main difference between selectors and filters?

  • Selectors are used to refine the content that filters have been applied to.
  • Selectors are used to find and select content in a page. Filters are used to refine the results of selectors.
  • Filters are used to remove content from the page. Selectors are used to add content to the page
  • There is no real difference. They are both used to build up lists of page content.

You want to create a custom right-click menu. How might you start the code?

  • $('#canvas').on('click.right', function(){ console.log('Handled a right-click') });
  • $('#canvas').on('contextual', function(){ console.log('Handled a right-click') });
  • $('#canvas').on('contextmenu', function(){ console.log('Handled a right-click') });
  • $('#canvas').on('rightclick', function(){ console.log('Handled a right-click') });

What is the correct way to check how many paragraphs exist on a page using jQuery?

  • $('p').count()
  • $('p').length
  • $('*').find('p')
  • $('p').length()

As with many areas of JavaScript, keeping track of the meaning of this is important and sometimes tricky. What does this mean at each of the two points in this custom plugin snippet?

$.fn.customPlugin = function() {
  // Point 1

  return this.each(function() {
    // Point 2
  • At Point 1, this means a jQuery object. At Point 2, it means a DOM element.
  • In this case, they mean the same thing: a jQuery object.
  • In this case, they mean the same thing: a DOM element.
  • At Point 1, this means a DOM element. At Point 2, it means a jQuery object.

How can you make the first list item bold and the next item oblique, in a single statement chain?

<ul class="menu-first">
  <li>Item 1</li>
  <li>Item 2</li>
  <li>Item 3</li>
  <li>Item 4</li>
  • [ ]
$('.menu-first > li')
  .css('font-weight', 'bold')
  .css('font-style', 'oblique');
  • [ ]
$('.menu-first > li')
  .css('font-weight', 'bold')
  .css('font-style', 'oblique');
  • [ ]
$('.menu-first > li')
  .css('font-weight', 'bold')
  .css('font-style', 'oblique');
  • [x]
$('.menu-first > li')
  .css('font-weight', 'bold')
  .css('font-style', 'oblique');

Which CSS selectors can you NOT use in jQuery?

  • You cannot use multiple class selectors such as .class1.class2.
  • You cannot use pseudo-classes such as :not or :last-of-type.
  • You cannot use IDs and classes together, such as #element.class.
  • None. All CSS selectors are compatible in jQuery.

Starting with some DOM elements in the nested structure below, you assign listeners for the same event to a child element and one of the parents using the JavaScript that follows. You want to ensure that when .leaf is clicked, only its event handler will be fired, instead of the click bubbling up and also firing the parent’s click handler. What do you need to add to its handler function?

<ul class="items" id="main-menu">
  <li>Item 1<ul>
    <li class="leaf">Sub Item 1</li>
    <li>Sub Item 2</li>
$('.leaf').click( function(event) { console.log('Sub Item 1 got a click'); } );
$('#main-menu').click( function(event) { console.log('Main menu got a click'); } );
  • event.capture();
  • event.stopPropagation();
  • event.preventDefault();
  • event.stop();

Using event delegation, you can listen for events on a lot of different items without having to attach separate listeners to each one. But there are times when you may want to check the type of item receiving the event before doing anything, such as checking if an image was clicked versus a text field. Given the starter code below, which choice shows what jQuery provides to help with that process?

<div id="sidebar">
  <img src="fancy-button.png" alt="Pick Me">
  <input type="text" placeholder="Fill in something">
$('#sidebar').click(function(evt) {
  var $target = $(;

  // What goes here?
  • $($target.get(0) + ':image')
  • $('img').is($target)
  • $target.filter('img')
  • $'img')

There are many ways to create elements that can be added to the page. Which answer is NOT one of those ways, assuming you have the following on the page?

<div id="elements"></div>
  • [ ]
$("#elements").append($('<p class="appended">As an HTML string</p>'));
  • [ ]
var p = document.createElement('p');
var text = document.createTextNode('As a DOM element');
  • [x]
$("#elements").append(<p class="appended">As a JSX object</p>);
  • [ ]
$("#elements").append($('<p>', {
  "class": 'appended',
  'text': "As an attribute object"

The .addClass() and .removeClass() methods can accept functions as arguments. What does this function do?

$('#menu').addClass(function() {
  return $('body').attr('class');
  • It adds the first class found on the body element to the #menu element.
  • It adds all classes found on the #menu element to the body tag.
  • It replaces any classes on the #menu element with all classes from the body tag.
  • It adds all classes found on the body element to the #menu element.

You’re working on a site that uses an old version of jQuery, and you want to update to a newer version. What’s the most efficient way to do so?

  • Install the newer version of jQuery, go through each script one by one, and fix what looks broken.
  • Read the change notes for the newer version of jQuery, fix all scripts, install the newer version, and fix anything that remains broken.
  • Install the newer version of jQuery as well as its Migrate plugin, fix all warnings, and uninstall the Migrate plugin.
  • Install the newer version of jQuery at the same time, and use jQuery.noConflict() on pages that need the older version.

Let’s say you have a page with just one link on it. How can you change the anchor tag so it links to

  • $('a').attribute('href', '')
  • $('a').attr('href', '')
  • $('a').data('href', '')
  • $('a').href('')

What does $() mean in jQuery?

  • It is an alias to the main core method of jQuery itself—the same as writing jQuery().
  • It is a utility function that selects the first element from the document.
  • It is a shorter way to write document.getElementById().
  • It is a utility function that selects the last element from the document.

Along with DOM traversal and manipulation, jQuery offers several general-purpose helper functions that fill in some JavaScript gaps, especially before ES2015. Which is NOT a jQuery utility function?

  • jQuery.each, a general purpose iterator for looping over arrays or objects
  • jQuery.isNumeric, which can check whether its argument is, or looks like, a number
  • jQuery.extend, which can merge objects and make complete deep copies of objects
  • jQuery.isMobile, which can tell whether the user is using a mobile browser

Given this set of checkboxes, how can you select the ones that have the phrase “sun” as part of the value?

<input type="checkbox" name="artists[]" value="sun-ra">
<input type="checkbox" name="artists[]" value="otis-redding">
<input type="checkbox" name="artists[]" value="captain-beefheart">
<input type="checkbox" name="artists[]" value="king-sunny-ade">
<input type="checkbox" name="artists[]" value="weather-report">
  • $('checkbox').val(/sun/);
  • $('input[value*="sun"]');
  • $('input[value|="sun"]');
  • $('input:checkbox').attr('value', '*sun*');

How can you get an AJAX request to go through without triggering any of jQuery’s AJAX events?

  • Set the type option to “none”.
  • Set the processData option to false.
  • Set a success callback that returns false.
  • Set the option “global” to false.

How do you change the current value of a text field with the class .form-item to “555-1212”?

  • $.val('.form-item', '555-1212');
  • $('.form-item').val('555-1212');
  • $('.form-item').data('value', '555-1212');
  • $('.form-item').set('value', '555-1212');

How would you fire a callback when any AJAX request on a page has completed?

  • $('body').ajaxComplete(function() { console.count('An AJAX request completed'); });
  • $(document).on('ajax-complete', function() { console.count('An AJAX request completed'); });
  • $('body').on('ajaxComplete', function() { console.count('An AJAX request completed'); });
  • $(document).ajaxComplete(function() { console.count('An AJAX request completed'); });

Given this set of checkboxes, how can you select the one with the value “blimp”?

<input type="checkbox" name="songs[]" value="satisfaction">
<input type="checkbox" name="songs[]" value="respect">
<input type="checkbox" name="songs[]" value="blimp">
<input type="checkbox" name="songs[]" value="saturn">
<input type="checkbox" name="songs[]" value="penguins">
  • $('input[value="blimp"]');
  • $('input[value!="blimp"]');
  • $('checkbox').val('blimp');
  • $('input:checkbox').attr('value', 'blimp');

Given this snippet of HTML and jQuery code, what does the jQuery do?

<ul class="menu">
  <li><a href="#" class="active">Home</a></li>
  <li><a href="#">Page 2</a></li>
<ul class="active submenu">
  <li><a href="#">Subpage 1</a></li>
  <li><a href="#">Subpage 2</a></li>
var m = $('.menu'), sm = $('.submenu');
m.css('font-weight', 'bold');
  • It makes all the menu items bold.
  • It throws an exception on line 3.
  • It makes the first set of menu items, not the second, bold.
  • It makes the second set of menu items, not the first, bold.

You want to take a block of type and animate it to a larger size with jQuery. The following HTML and JavaScript behaves strangely. What is the issue?

<div id="type" style="font: 1em/1.5 helvetica, arial, sans-serif; background: #ffc; padding: 0">
  Animate me!
  fontSize: '+=1em'
}, 3000);
  • jQuery does not support ems and will make the type 1 pixel larger instead of 1 em larger.
  • jQuery cannot override CSS in a style attribute, so the font size will not change.
  • The font size was set with a shorthand property, so jQuery will not animate the font size at all.
  • The font size was set with a shorthand property, so jQuery will start the animation from 0 instead of from 1 em.

When using the clone() function to duplicate an element, what is one of the main concerns your code needs to watch out for?

  • The clone() function may ignore data attributes on the original elements.
  • The clone() function may result in elements with duplicate ID attributes.
  • The clone() function may remove CSS classes from the cloned elements.
  • The clone() function may not respect the attribute order of the original elements.

When incorporating a plugin into a project, what are the important steps for basic installation and usage?

  • The jQuery script tag must come first, followed by the plugin, followed by your custom scripts, all preferably at or near the bottom of the page.
  • Your custom scripts must appear first in the document <head>, followed by jQuery, followed by the plugin.
  • The jQuery script tag and the plugin script tag must appear in the document <head>, and your custom scripts can follow anywhere on the page.
  • The jQuery script tag must appear in the document <head>, but the plugin and your custom scripts can appear anywhere else in any order.

These two script tags show different ways of using jQuery’s ready() method. What is true about both approaches?

  $(function() {
    // The rest of my code goes here

  jQuery(document).ready(function($) {
    // The rest of my code goes here
  • The code inside them can manipulate the DOM safely, knowing the browser has loaded it fully.
  • The code inside them can manipulate images on the page safely, knowing they have fully downloaded to the browser.
  • The code inside them will be run exactly once per user session.
  • The code inside them is not aware of the DOM.

Which property of the jQuery event object references the DOM object that dispatched an event?

  • self
  • target
  • object
  • source

Which describes how jQuery makes working with the DOM faster?

  • jQuery optimizes the DOM in a background thread, making updates faster.
  • jQuery avoids using the DOM at all.
  • jQuery uses a virtual DOM that batches updates, making inserts and deletes faster.
  • jQuery code to perform DOM manipulation is shorter and easier to write, but does not make DOM operations faster.

There are some issues with this snippet of jQuery. First, it is manipulating CSS directly, rather than manipulating classes and leaving the CSS in stylesheets. What else in this code is best to avoid?

$('.item').css('background-color', 'red');
// some other code here
var firstSubItem = $('.item').find('.sub-item').get(0);
// some other code here too
$('.item').parents('.navigation').css('font-weight', 'bold');
  • The .css() method accepts only an object, not two separate arguments. This will trigger an exception that should be caught.
  • The $('.item') selection is being made several times. This should be cached in a variable for (however slightly) better performance and easier maintainability.
  • The call to .parents() is in an inefficient place.
  • All the calls to $('.item') should be chained together as a single executable line for better performance.

Which choice is an example of statement chaining?

  • var $p = $('p'); console.log($p.length);
  • $('p').find('a').children('li');
  • $('p > a > li');
  • $('p'); $('a'); $('li');

How can you ensure that some code executes only when a class active appears on an element?

  • $('.element').attr('class', 'active')
  • $('.element').with('.active')
  • $('.element').hasClass('active')
  • $('.active').then()

jQuery has a main function for handling AJAX, and several shorthand function including load() that make calling that main function easier. Given this HTML snippet, how can you insert only the second snippet from the source.html file (div#one) into the #load-me div on-demand via AJAX?

<div id="load-me">
  This area will be replaced with AJAX loaded content.

<div id="one">
  <h1>First Piece</h1>

    Lorem ipsum duis maximus quam condimentum dolor eleifend scelerisque.

<div id="two">
  <h1>Second Piece</h1>

    Lorem ipsum proin facilisis augue in risus interdum ornare.
  • $('#load-me').get('source.html#one');
  • $('#load-me').get('source.html #one');
  • $('#load-me').load('source.html #one');
  • $('#load-me').load('source.html', '#one');

Given this HTML list and subsequent two lines of jQuery, what is the difference in the behavior of .closest() and .parents()?

<ul class="items" id="main-menu">
  <li>Item 1 <ul id="sub-menu">
  <li class="leaf">Sub Item 1</li>
  <li>Sub Item 2</li>
  • .closest() returns .leaf and #main-menu; .parents() returns #main-menu and #sub-menu.
  • .closest() returns .leaf and #sub-menu; .parents() returns #main-menu and #sub-menu.
  • .closest() returns only #main-menu; .parents() returns #main-menu and #sub-menu.
  • .closest() returns only #sub-menu; .parents() returns #main-menu and #sub-menu.

What does this line of code do?

$('ul > li:first-child');
  • selects the first list item inside all unordered lists on the page
  • selects the first list item inside the first unordered list on the page
  • selects the first element inside any list items on the page
  • creates a predefined CSS selector that can be reused later

Below is a list of items that you want to be clickable and an event handler function. How can you assign the event handler to every item in the list in a way that is most performant, and also that ensures that the handler is called even if more items are added to the list programmatically?

<ul class="clickable-list">
  <li>First Item</li>
  <li>Second Item</li>
  <li>Third Item</li>
  <li>Fourth Item</li>
  <li>Fifth Item</li>

Do’s And Don’ts On Your First Job Interview

In this way, your first historically job interview has been booked and your psyche is conjuring up a wide range of best and most pessimistic scenario situations of what’s in store. Will it be a short, windy, and casual visit finishing with a strong handshake and a job offer? Or on the other hand, will you be met with a board of harsh faces who will go through one hour cross-examining you as you break out into cold sweats? 

Most would agree that your first job interview can appear to be a mystery, subsequently why I have chosen to give you some clarity: 

Interviews are a two-way discussion 

Along these lines, we should begin with why you are being interviewed. The interviewer needs to a) see if you are a solid match as far as abilities, potential, and character, and b) have you with a positive impression of the organization and opportunity. They won’t accomplish both of these things if you have a negative experience and don’t feel great to perform at your best. Subsequently, expect and get ready for less cross-examination, and to a greater extent a two-way discussion whereby you both evaluate each other’s propriety. 

What’s more, likewise with anything, planning on the two sides is the way into an effective interview. Along these lines, in front of your first job interview, I would inform you that you plan for each regarding the stages laid out beneath, looking for the help of your recruiter where fundamental: 

Stage 1: Arriving at the reception 

Your appearance is your first opportunity to show your certainty and polished skill, and even this piece of the interview needs groundbreaking. 

Prior to the interview, your recruiter will have given you the critical data about the number of individuals you will meet, their complete names and job titles, at what time, and where. Have this data spared both on your telephone and printed out for reference. I would likewise propose that you: 

Plan your course, show up at any rate 15 minutes ahead of schedule, and set aside a few minutes for surprising deferrals.

Pick your outfit ahead of time, ensuring you have keen interview clothing, regardless of whether the worker clothing standard is casual. 

Welcome the interviewer in a manner that oozes confidence; that is, with a wide grin, solid handshake, and an upstanding posture. 

While holding up in gathering, sit upright, oppose the impulse to use your cell phone and some other individual gadgets, and be respectful to the assistant and any other person you come into contact with. 

Stage 2: The start of your first historically speaking job interview 

Presently, onto the interview itself. You will be taken to a private and calm space by your interviewer(s) and they will probably offer you a beverage – I recommend that you request water if you don’t have any with you, in case you need to get some time and take a taste when pondering your answers. 

Whenever you’re sat in the interview room, your interviewer will present themselves, and in all probability get some information about the organization. They’ll need to watch that you are eager about this job and that you care enough to have done your examination. 

There’s no reason for not getting your work done in this age of digitalization, so a couple of days before the interview, plan to discuss the beneath in your own words. Ensure you show a certifiable interest, featuring whatever you discovered especially noteworthy and requesting that your enrollment specialist explain anything you’re not sure on: 

How the organization framed, when, why, and by whom. This data should be accessible on the organization history segment of the site. 

Their particular items and administrations, in addition to their qualities and remarkable selling, focus as an association.

Any ongoing triumphs and missions. Investigate their social media pages to improve thought.

Your interviewer will at that point proceed to talk somewhat more about the job, and how this finds a way into the more extensive business, hence it would likewise be a smart thought to bring a notebook and pen so you can write down any inquiries that you need to pose toward the end. 

Stage 3: Talking the interviewer through your CV 

Next, your interviewer will request that you talk through your CV. This is on the grounds that they need you to disclose to them the account of your vocation to date, and essentially what’s directed to you sitting before them today. 

Visit ATS resume template for Latest Resume Templates.

In view of this, carry a duplicate of your CV with you to the interview for reference, and plan ahead so you can interface this highly contrasting record to the job you are applying for: 

Choose which parts of your CV you need to just give a feature diagram of, and which to really expound on. For instance, you might be applying for a sales job. Accordingly, you would talk more about your retail internship and previous jobs rather than accomplishments in any other field.

Plan to clarify any gaps in your CV. Regardless of whether you were traveling, studying or job looking – let the interviewer realize that you were accomplishing something.

Pick the zones of your CV to expound on by featuring the interests, scholarly accomplishments, and extracurricular exercises that identify with the job, especially any adaptable aptitudes learned here. 

Finish up by clarifying how your excursion so far has driven you here today and why you’re keen on the chance. 

Taking into account that this is your first job interview, you very likely have restricted insight, thusly you may feel stressed that you don’t have a very remarkable story to tell. You do. You simply need to arrange for how to tell it. 

Stage 4: Answering the interviewer’s inquiries 

Following on from this, your interviewer will have arranged a bunch of inquiries to pose to you with the goal that they can evaluate your appropriateness for the job. These inquiries will gauge your key capabilities, your capability to prevail in the job, and whether you would be a decent character fit. 

Considering this, it is in both of your inclinations that you answer genuinely and don’t misrepresent your abilities and experience. Simultaneously, you will have some incredible qualities to your name – so don’t be hesitant to sing your own praises by the same token! 

Get ready by exploring the most generally asked interview inquiries, for example, “For what reason do you think you are appropriate for this job?” Plan the central issues to remember for your answers heretofore, and recollect these rules and regulations: 

DO: Speak politely and clearly.

DO: Maintain a decent posture, solid eye to eye contact, and an open smile.

DO: Back up any cases about your abilities with proof of these aptitudes in real life.

DO: Relate your answers back to how they would be valuable to the job.

DO: Have a structure in your psyche for your interview answers to prevent you from meandering aimlessly or going thinking about something else. Work on responding to some interview addresses adhering to this system. 

Try not to: Answer any inquiry with “I don’t know”. Pose the interviewer to reframe the question or express it distinctively if you didn’t understand.

Try not to: Speak adversely about any of your encounters. Certain inquiries may provoke this, for example: “For what reason did you find employment elsewhere in retail?” While we empower straightforwardness, you likewise should be proficient and positive.

Try not to: Interrupt. Pause for a second subsequent to being asked an interview inquiry to check the interviewer has got done with talking. This will likewise offer you one moment to consider your responses. 

If you haven’t as of now, ask a companion, relative, or your selection representative to go through some training interview inquiries with you previously. Your selection representative can give you a superior thought of the sorts of inquiries to expect, just as helpful criticism on your answers. 

Stage 5: Asking the interviewer any inquiries you have 

Next, you will be approached if you have any inquiries for the interviewer. Try not to think little of the significance of this piece of the interview. Your interviewer needs to realize that you are keen on the job, and set aside the effort to set up certain inquiries so you could discover more. Having said that, there are acceptable inquiries to pose, and terrible inquiries to pose, and it is fundamental that you comprehend the distinction before you go up to the interview. For instance: 

DO: Ask inquiries regarding your job, e.g.- “How has this job developed?” 

DO: Ask inquiries concerning the organization that couldn’t undoubtedly be discovered on the web, e.g.- “How might you portray the organization culture?” 

Try not to: Ask individual inquiries regarding the interviewer, for example – “How old would you say you are?” 

Try not to: Ask questions that start with “Would I have to?” This shows hesitance and sounds negative.

Try not to: Ask inquiries concerning occasions, advantages, and compensation. This could sound arrogant and will be brought by means of your recruiter later down the line at any rate.

Stage 6: Leaving your first job interview 

At long last, your interviewer will in all probability wrap up the interview by affirming the following phases of the cycle. Now, they are dealing with your expectations, as they may have a couple of different possibilities to see, and the decision-making process can require significant time. You can likewise consider this to be your opportunity to have a decent last effect, so make sure to thank the interviewer for their time, and affirm your advantage in the job. 

After your interview, call your recruiter for criticism on how you think it went. They may well give you some criticism from the interviewer as well, so make note of this. I would likewise exhort that you send a subsequent email for the selection representative to pass to the interviewer, by and by expressing gratitude toward them for their time and emphasizing your advantage. 

Stage 7: Following up after your first job interview 

Throughout the following not many days you ought to hear back from your selection representative, so keep your phone close by with the volume turned on, and browse your emails routinely. Fingers crossed you get some uplifting news; either that you are through to the following round of interviews, or far better, you have been extended to the employment opportunity!

If it’s bad news, offer yourself a break, all things considered, this is your first job interview! Ensure you discover why you weren’t offered the position, accepting both the positive and not all that positive criticism, so you can improve your interview strategy for next time. Stay in contact with your recruiter, on the grounds that at this stage, they definitely understand what you are searching for and what you have to bring to the table, and they can put you forward for other appropriate jobs. 

I hope I have helped facilitate a portion of your nerves in front of your first historically speaking job interview, and the greater part of your dread was simply dread of the obscure. Keep in mind, if you realize what to envision, and how best to plan for each stage, you are in with a solid possibility of getting to the following stage simultaneously. If not, utilize the experience as an expectation to absorb information and a venturing stone towards future interview achievement.

7 Need-to-Know Salary Negotiation Skills

There is no single reading material way to deal with salary negotiations, so it’s essential to be profoundly mindful of your current circumstance, your value, and your field prior to going into them. 

Salary negotiations are not a fight. Realizing how to negotiate a higher salary involves agreeing with your boss and you will encounter the most ideal result. 

1) Look Confident (regardless of whether don’t feel it) 

Put on that game face. You need to show up absolutely certain about the position you are taking inside the negotiations. Try not to settle. Know your value and remember why you mentioned a salary negotiation in any case. 

Keep in mind that negotiations are frequently opened at the lower end of the salary range, for the straightforward explanation that employees or up-and-comers are relied upon to haggle for something more serious.

2) Resist making — or accepting — the primary offer 

If you are straightforwardly asked what your salary prerequisites are, attempt to try not to express a careful figure.

  • “Other than the base salary, what other advantages are debatable?” These advantages may incorporate education and training, medical insurance, vacation time, paid leave, and moving expenses. Likewise, remember that your salary may not decisively be up for exchange — yet this doesn’t mean your benefits package won’t be. 
  • “What measurements do you use to assess a worker’s success?” Having this data to hand can deliver you extraordinary profits whenever you wind up back at the arranging table. 

4) Come with a salary range, not a solitary figure 

If that you are squeezed for your salary necessities, guarantee that you generally offer a reach, in light of what others in the field are acquiring. You can obtain this information from your very own examination, which you can depend on to educate your arranging position and strategy. Being adaptable, rather than adhering ardently to a solitary figure, encourages you in your negotiations as a rule and furthermore permits you to all the more effectively arrive at a trade-off.

If you are jobless and looking for work, it’s more reasonable to hope to acquire around your old salary, maybe even somewhat less, than it is to hope to go in after a break from work and quickly be earning more than you used to.

7) Don’t avoid showing your worth 

If your counteroffer is dismissed, be prepared to clarify definitely why you accept your solicitation is, truth be told, legitimized. Show exactly how the organization would profit from your ability by referring to clear and noteworthy instances of how you have increased the value of your previous (and current) work environments. Demonstrate that you have genuinely and truly assessed and concentrated each aspect of your salary.

Pay negotiations are a vital part of each representative’s vocation at some stage. However long you’re readied, sure, agreeable, proficient, and genuine, you won’t go far wrong.

Magento 2 Migration: An Interview With an Expert

Now that the official support of the Magento 1 platform has come to its end, the question of Magento migration is more debated than ever. Especially keeping in mind the complexity of the “moving” process from the technical perspective on the one side and the outstanding advancement opportunities that it can bring, including the chance to build progressive web applications on the basis of Magento 2, on the other.

Therefore, if you’re a business owner with a store up on Magento 1 who is in two minds about whether you should migrate to Magento 2 or not, this interview can help you “dot the I’s and cross the T’s”. We’ve interviewed an experienced Magento expert and Chief Technology Officer at Onilab, Alex Husar, and asked him the most often occurring questions regarding Magento 1 migration to Magento 2. Below you’re welcome to read what we’ve learned!

Why migrate to Magento 2 if the site works fine on the 1st version of the platform?

Well, perhaps, the fairest answer to this question is that you’ll still have to go for migration sooner or later. Yes, your store may be functioning and performing well at the moment, and the truth is that you can keep the store up on Magento 1 for a while, there is no ASAP rush. But the site will become incompatible in a year or so whether you like it or not.

And since the migration procedure is rather complicated and quite time-consuming, you must keep in mind the large time frames ahead if you do decide to move.

Plus, after some time passes, it’ll become more and more difficult to keep up your Magento 1 store and add new functionality to it. Mainly because the Magento team stopped releasing updates and modules for this version of the store, switching their focus completely on Magento 2. So, if you’d want to add some features to M1, you’d face the need for custom solutions.

In any case, the move to Magento 2 brings tons of opportunities. You can re-think the store’s design and visuals, improve your navigation, add new features that deal with SEO, mobile optimization, neater checkout solutions, etc. You may even take advantage of the chance to create a PWA application after the move to M2 (no such chance with PWAs on M1, by the way).

At the end of the day, all of this modernization and advancement can lead to a new and improved store with enhanced performance and better conversions. So I guess I’d say what’s the point of delaying?

Can a Magento 1 store face hazards if you don’t migrate?

Definitely! Because the official Magento team won’t be releasing nor updating the security patches for the first version of the platform anymore, it’s vital to understand that the longer you stay on Magento 1, the more you’re jeopardizing your eCommerce site.


The things that you should worry about here are the possible hacks and other vulnerabilities of the store that can occur due to this. Without proper “defense”, your site can become easier to “attack”. Let me give you an example to back this idea up.

For instance, you surely don’t want to fall prey to some fraudulent activity that’ll lead to data leaks. As a store owner, you take full responsibility for keeping safe the data that your customers trusted you with (this includes their personal information like their delivery address, contact details, and even more so, payment details). If this information leaks on your fault, such a scenario can lead you to heavy and costly legal consequences.

This is one of the main reasons I’d suggest not to postpone the migration question.

So why do many business owners procrastinate their migration to Magento 2?

I assume this is because they might not see the point in it or don’t get why it’s necessary. Say, they enjoy the store just the way it is and are afraid that it’ll hurt it rather than help it.

Or they might not know how not migrating can harm their business. Another reason could be, perhaps, that they don’t have the budget for migration and are saving up for doing it later.

They can even be thinking about switching from Magento to some different eCommerce platform altogether. There are many probable reasons, really, each case is individual.

But what most Magento store owners don’t quite understand is that the first and second versions of the platform are very different technically, it’s like comparing the moon and the sun. Magento 1 and Magento 2 have very few things in common, apart from the name. This means that the migration process isn’t easy and requires experienced certified Magento developers who know both of the platforms, their differences, and other migration peculiarities.

Therefore before making a final decision to put off migration to M2, bear in mind that the procedure isn’t simple, implies the work of strong experienced specialists, and a deal of time.

And how long can migration from Magento 1 to 2 take?

The time frames for migration from Magento 1 to Magento 2 is a very individual question. The required hours of development will depend on a plethora of factors. These include how highly-customized the eCommerce store is, how large it is (including in terms of database volumes and logs), how many third-party modules it has, and, of course, how many new features are needed on the website after migration.

It’s very rare that a site owner wishes to just transfer the store from M1 to M2 without making any additional improvements to it. But even if this is the case, count on at least two to four months. If you’re planning on implementing new features and improving the site, then we’re talking about four months and up (again, the more new stuff you want and the harder it is to build, the more time will be needed). If you want to get a PWA that everyone’s recently craving, then add on several more months into the equation.

What are the most common Magento 2 migration issues?

To be fair, many things can go wrong during the process. It’s not like you copy what the Magento 1 store has and paste it on to Magento 2. This procedure requires lots of work, configuration, set-ups, untangling, and debugging.

As a rule, a lot of inexperienced teams underestimate the volumes ahead during the planning and evaluation stage. Because the two platforms have too many dissimilarities in terms of their architecture, it can get tricky to get things right. Therefore, thorough planning of the work ahead is an important step not to overlook as it can arise issues.

Not everything will be moved either, for instance, you might not need some logs from a decade ago or some of the currently used features. So, you’ll be sorting some parts of the site and deciding what to “take with you” to the second Magento. Likewise, the Magento 2 database migration generally presents an additional difficulty.

The challenge with the compatibility of modules is among the toughest that the team deals with. Every store contains various plugins, be it SEO, emails, payment methods, etc. Some of these modules are released by Magento, others are from third-parties or even coded uniquely for the store. Developers must find analogs to replace the modules on Magento 2 (since the ones on Magento 1 won’t work) and spend time configuring them. In situations when no equivalents are present, these solutions have to be coded from scratch.

What else? The re-design usually takes a while as well. New features to be added extend further development. Moreover, the same applies to any custom solutions that you’ll need.

Frankly, one more issue with migration that can be faced is hiring the wrong people for the job. If your team isn’t familiar with both of the platforms well enough or lacks previous migration experience, this can knot up and complexify the whole process to a big extent. This is why you shouldn’t hurry when looking for a development team for migration who you can trust. 

Final Thoughts

Summing up the above, according to the expert opinion given in this article, migration to Magento 2 from Magento 1 has more ups than downsides. Although the process of migration isn’t simple in itself nor is it fast, a qualified team can help you boost your eCommerce store, make it more modern, compatible, and safe. Hope that this Q&A has de-veiled answers to some commonly occurring doubts. Don’t hesitate to reach out to us if you have more questions on the subject!

Automation Testing Interview Questions

Are you a software geek preparing for an interview? Well, we wish you a hearty, ‘All the best!’ 

Nervous? About What? Automation testing! Here are some questions you need to prepare to ace an interview!  

Test automation has an essential role to play in the entire software development lifecycle.  

A lot of times when people prepare for an automation testing interview, they focus only on the automation tool-specific questions.

However, people should also consider the fact that learning and knowing about the automation tools is not the same as knowing about the automation testing and hence it’s not the ultimate goal. 

 Thus, whenever you are preparing for a ‘test automation’ interview, it is essential for you to consider ‘Automation’ as a whole and focus on its framework and all the steps involved. 


What are automation and automation testing? 

 Automation is any form of action that can help reduce human effort. 

Automation testing is of course, automated. This is completely different from manual testing as in manual testing, a human is responsible for testing the functionality of the software in the way a user would. 

Automation testing is a software testing method used to test and compare the expected outcomes with the actual outcomes. It is achieved by using automation tools or by writing test scripts. 

Automation testing is used to automate testing tasks that are difficult to perform manually like repetitive tasks. It requires far less time than manual testing due to the fact that automation testing is done with the help of an automation tool while humans perform manual testing. Less time is needed in exploratory tests and more time is needed in maintaining test scripts while increasing overall test coverage just like mystery rooms.


What are the tests that can be automated? 

Following are the things/tests that can be automated: 

  • Build deployment 
  • Test data creation 
  • Regression test suite 
  • Smoke / Sanity test suite 

Automating behind the graphical user interface like testing of APIs. 


Is test automation useful or not? 

Automation testing proves to be useful in the following scenarios: 

Non-functional Testing: Automation-testing is used to test the non-functional aspects of an application. 

For Example, Performance testing and load testing are very difficult tasks for humans to track and analyze. 

Regression Testing: Regression testing is done in case of a bug fix or new module implementation, then is important to make sure that the already implemented and unchanged functionality is not affected in any manner. In this case, the people end up running the regression test multiple times. 

For Example: After each change request or bug fix and after every iteration in the case of the incremental development approach. 

Repeated execution of the same tests: Sometimes, it is important to run the same set of test cases for a different set of data. Also, after each build release or on multiple hardware and software or a combination of hardware and software. 

Automating the test cases in the above scenarios helps in maximising the speed of testing and minimising human errors. 

Complex calculation: Automation testing in this case helps in checking or testing scenarios that are prone to human errors. 


 Is it possible to achieve 100% automation? 

100% automation is difficult to achieve because then there will be a lot of edge test cases and some cases that are not executed very often. Automating these test cases which are not executed very often will not be able to add value to the automated suite. 


How can we identify the test cases which are suitable for automation? 

The most important step towards automation testing is the identification of the most appropriate test cases for automation. 


How to decide the automation tool that one should use for their Automation testing in the projects? 

To identify the best tool for Automation testing for your project you need to do the following: 

  1. You need to understand your project requirements thoroughly and identify the testing scenarios that you want to automate. 
  2. Lookup and search for the list of tools that support your project’s requirements. 
  3. Plan out your budget for the automation tool. Then, choose the tools within your budget. 
  4. Be sure that you already have skilled resources for using the automation tools. If you don’t have the necessary skilled resources for using the automation tool then identify the cost for training the existing resources or hiring new resources for the work. 
  5. Compare each automation tool with the key criteria: 
  6. Once you have compared the best automation tools for your purpose, select the tool which is within your budget and supports your project requirement, and gives you more advantage based on the key criteria. 


What are the key criteria for automation testing tools? 


The key criterion for automation testing tools is as follows: 

Does the automation tool have test reporting functionality? If not, can it be easily configured to the tool? Is that automation tool suitable for cross-browser support for web-based applications? How many different testing types can the tool support? 

  • How many languages does this automation tool support? 
  • Is it easy to develop and maintain the scripts for the tool? 
  • Can a non-technical person also execute the test cases with some simple training? 

Is the tool able to support different types of platforms like web, mobile, desktop, and much more based on your project requirements? 


What is the next step after deciding the automation tool to use? 

Once the tool is finalised, the next step is to design the framework. 

What is the framework? 

A framework is a part of the structure of the entire automation suite. It is also a guideline, which when followed properly, can result in a structure that is easily maintained and enhanced. 

The guideline of the framework includes: 

  • Handling of environment files and properties file 
  • Reporting of data 
  • Handling logs 
  • Coding standards 
  • Handling the test data 
  • Maintaining and handling the elements (object repository in QTP) 


Final Words: 

The questions above are the main questions that are important for automation tools or programming language. Automation testing interviews also include tool and programming language-specific questions depending upon the tool that the people have worked with. 

Most of the test automation interview questions are centered on the framework that the person develops, so it is recommended that everyone creates and understands their test framework thoroughly. 

Have you gone through all the Q&A? Now, get ready and crack any software interview!

ECMAScript 6 is also known as ES6 and ECMAScript 2015 or Simply JavaScript 6. ES6 is new version of JavaScript and having many new features. The new features of ES6 making JavaScript a New Age Scripting language.

The ES6 is the sixth edition of the language and was released on June 2015. It was initally known as ECMAScript 6 (ES6) and later renamed to ECMAScript 2015. This edition includes many new features like class, modules, iterators, for/of loop, arrow functions, typed arrays, promises, reflection.

ES6 has following new features included:

  • JavaScript let
  • JavaScript const
  • JavaScript Arrow Functions
  • JavaScript Classes
  • Default parameter values
  • Array.find()
  • Array.findIndex()
  • Exponentiation (**) (ECMAScript 2016)


What is difference between JavaScript and es6?

JavaScript is the language. ES (ECMAScript) is the standard governing JavaScript. ES6 is the version of ECMAScript draft in which a lot of features were introduced (classes, arrow functions etc). … JavaScript is an language whereas ES6 is an ECMAScript’s 6th edition. (Answer From Quora)

What are the new features of ES6?

ES6 comes with many new and prompt features like:

  • Immutable variables or constants are now supported
  • Arrow Function
  • Parameter Handling Extended
  • Modules and Classes
  • Extended Object Properties
  • Internationalisation and Localisation

What is Arrow function?

Arrow functions support expressions bodies and statement bodies which returns the value of an expression and makes the syntax more expressive. Arrow functions have lexical ‘this’ feature as well. Arrow (=>) is used as part of the syntax. Lexical this is declared or defined where the function is written. It comes under the umbrella of lexical scope; lexical scope has access to variables that are in its parent scope.


//Implementation With Classical Funnction
function add(a,b){
return a+b;

//Implementation With Arrow Funnction
const add = (a,b) => a+b;

Differences amongst classes, modules, and proxies?

Proxies enables object creation with a wide variety of behaviours available to host objects. It can be used for logging, profiling, etc.

Module defines the patterns from popular JavaScript module loaders. It supports exporting or importing the values from or to modules without the global namespace. It supports marking the value as the default exported value and max-min values.

Classes are based on the Object Oriented Programming style that is object-oriented programming. The class declaration makes the patterns easier to use. It supports inheritance, base class access, static methods, and constructors.

List data types supported by ES6?

JavaScript supports : Number, Boolean, String, null, undefined, Symbol and Object.

What are the Differences Between ES6 vs ES5?

ES6 : there are two new ways to define variables that are let and const.
ES5 : we could only define the variables by using the var keyword.

ES5 : both function and return keywords are used to define a function.
ES6 : An arrow function is a new feature introduced in ES6 by which we don’t require the function keyword to define the function.

ES5 : It supports primitive data types that are string, number, boolean, null, and undefined.
ES6 : There are some additions to JavaScript data types. It introduced a new primitive data type ‘symbol’ for supporting unique values.

How to Define a Constant in ES6?

In ES6, a constant is defined by a const keyword. ES6 provides a const keyword, which a constant uses and declare a const.

What is Webpack?

Webpack allows you to run an environment that hosts babel. Webpack is opensource JavaScript module bundler that takes modules with dependencies and generates static assets representing those modules.

What are the main benefits of Web pack in ES6?

Benefits of Web pack in ES6:

  • It has included dev server.
  • You only require including one JS tag sharp to server like localhost:8080/assets/bundle.js and get live system updating and advantage management in no costs.
  • Multiple modules and packs are bundled into a solo .js file.

What is Set?

Set are objects and collections of unique values. Duplicate values are ignored, as the collection must have all unique values. The values can be primitive types or object references.
NOTE : NaN and undefined can also be stored in a Set. NaN is considered the same as NaN (even though NaN !== NaN).

What is Spread Operator in ES6?

Spread Operator provides a new way to manipulate array and objects in Es6.A Spread operator is represented by … followed by the variable name.
Example :

let a =[7,8,9];
let b=[1,2,3,...a,10];
console.log(b); // [1,2,3,7,8,9,10]

So spread operator spreads the contents of variable a and concatenates it in b.

Another Example

function print(...z){

7 Important Ways Data Science Helps Human

The industries of healthcare and finance have one thing in common: they are both getting highly interrupted with the advancement of technology, namely data science. And this phenomenon is being highly encouraged as Data Science Helps Human.

In 2017 alone, 3.5 million USD was invested in over 180 health companies. The core of significant transformation in the health industry, therefore, lies in data science. 

More than a billion clinical records are being created, for instance, in the US every year. Doctors and life scientists have an immense amount of data to base their studies on.

Moreover, immense volumes of information related to health are made available through the large-scale choice of wearable gadgets. This opens the door to new innovations for more informed, better healthcare.

The main objective for health data scientists working with the healthcare industry is to make sense of this huge data set and derive helpful insights from it so the human body and its issues can be understood better by healthcare providers. Therefore, data science can strongly transform healthcare. 

Let us look at 7 benefits of Data Science

Wearable to Monitor and Prevent

Human bodies produce two terabytes worth of data daily. Due to technological advances, it is possible to collect most of this data such as heart rates, blood glucose levels, sleep patterns, stress levels, brain activity, etc. Armed with such volumes of data, data scientists are expediting the limits in health monitoring. 

Among the leading tech companies in the world like Qualcomm and IBM, have been pioneering the path to health innovations. Apple too joined this race in 2015 with Research Kit.

Another issue in healthcare that requires special attention and regular observation is the management of chronic diseases. Omada Health targeted this specific issue and opened its first product, which is a preventive medicine plan. This plan aims at transforming the lifestyles of their patients and helps them manage their weight and prevent the dangerous effects of obesity. Both businesses and individuals have adopted it.

Improving Diagnostics

Despite such enormous quantities of health data at disposal, the rates of diagnostic failure are still comparatively high. For this case, let’s look at Bruxlab, a Dutch startup, which applies machine learning and data science for diagnostic purposes. Combined with technologies of sound recognition, they diagnose and grade Bruxism symptoms. Bruxism is quite a common disorder but it is overlooked because its symptoms are concealed. Therefore, a mobile app now, helped with data science, presents a way to better diagnose and monitor a disorder.

Transforming Patient Care

The way which scientists gather and evaluate health data when they are looking for symptoms to identify diseases, doctors can do the same with patients and track their clinical duration to confirm their diagnosis. Informed care and personalized treatment, driven by technology can eliminate death rates significantly and develop precise patient records.

From EHR (Electronic Health Records) adoption to genome sequencing improvement, doctors and other health providers now have a lot of data at hand to determine continuous symptom patterns and help add to patient records.

A good example of data science application is to assist healthcare providers to treat their patients better is Oncora Medical. This startup uses archival data from several cancer treatment clinics and the patient’s unique EHR data to offer customized treatment suggestions, depending on the cancer type, previous health reports, and their current condition. 

Advancing Research

Cancer is among the deadliest and the most common diseases in the world. It has been a consistent subject for research. The number of people getting afflicted by the disease is growing consistently. A healthcare startup in Boston named BERG Health has reshaped cancer medication through inclusive data science application. They use strong algorithms of machine learning they have extracted and evaluated from biological samples provided by more than a thousand patients. With more than 14 trillion information points included in every sample, BERG had enough data to input into the artificial intelligence algorithm.

This resulted in BERG developing the drug BPM 31510 that identifies and triggers the natural damaged cell death by cancer. While testing is still going on regarding the drug, it is clear that data science has transformative potential and technologies of machine learning can greatly contribute to the pharma industry. If this can cause breakthroughs in cancer, then imagine what it can do for other diseases like Ebola or HIV AIDS. 

For Efficient Clinical Performance

Predictive analytics and data science is an invaluable tool that can support healthcare providers to enhance the process through which hospital operations are accomplished. A startup from Austin, Texas, CognitiveScale, employs machine learning to enterprise processes in certain industries, including retails, healthcare, and finance. They offer two services: Engage and Amplify. Both are utilized regularly by company level organizations and managed to understand the data sourced from both employees and clients. Thus, the plans give important suggestions and actionable outputs, advancing the organizations to improve production and action.

In the same way, data science can be applied to enhance clinical staff schedules and decrease wait times, manage accounting and supplies, and even develop an efficient engagement plan for epidemics like seasonal flu. 

Reducing Risks in Prescription Medicine

An innovative startup named MedAware aims to reduce errors in prescription. The startup claims to have tools that will allow hospitals to save almost 5.6 million USD and eliminate the danger of lethal results. This software system is self-learning; it checks every prescription by comparing it to similar cases stored in the database and lets the doctor know if there are any deviations in the prescriptions.

Cutting Down on Hospital Re-admissions

Complete digitization and transformation through technology help save many industries a lot of money, and it is the same in the healthcare industry as well. 

Preventive medicine based on analytics can contribute to the complete reduction of costs, indirectly though. For instance, Clover Health, which is an analytic health insurance company driven by data, claims up to 50% fewer hospital admissions. They use a smart algorithm that identifies at-risk patients and helps orchestrate the required care. Thus, Clover Health saves almost 10,000 USD per each admission on an average.

Moreover, the application of data processing and interpretation mechanisms enables physicians to secure educated decisions, which follows in meaningful profits. For example, data analytics, used to enhance the knee replacement surgery let healthcare providers save more than 1.2 million USD in a year

From foretelling treatment results to counteracting cancer and delivering more effective patient care, data science healthcare has shown to be a valuable addition to the industry’s future. While data science gives methods and tools to obtain authentic content from unregulated patient data, it ultimately provides healthcare more effective, convenient and customised.

Things to Consider Before Accepting a Job Offer

Landing a job that fits your style and is compatible with your values starts with a resume that effectively translates your skills and qualifications into writing. By possessing the right resume , you will attract the right employers suited for the career you are gunning for.

Crafting the right resume is not an easy undertaking, but with the proper guidance, it becomes effortless. But if you’re starting out your career, you need to start with a good resume too.  

Securing a job is one of the most significant accomplishments in the life of an adult. It gives the job seeker feelings of achievement, confidence, and value when you get that email saying, “Congratulations!” with a job offer attached, listing what you get in exchange for your services. 

Salary is the number one factor that candidates focus on when deciding whether they will accept a job offer. Fair enough. However, while one’s annual wage covers the basic expenses and bills, consider other factors that are equally as important before saying “yes” to the offer.


Regardless of the job level or the industry your career is in, no job is perfect. All jobs come with baggage that can significantly affect your work performance and your life outside of it. Before jumping at the opportunity to accept the job offer, make sure you have a clear understanding of what the job comes with. You can 

Will you be working on the weekends? Are long work hours expected even though the job description states a 9–5 schedule? Will you be on-call 24/7? Will you be working with a department, or are you expected to tackle these responsibilities as a one-person entity? 

For finance positions, the main baggage is that you’re never fully off-duty. As an executive, being “on” 24/7, attending spur-of-the-moment meetings, answering off-duty phone calls, or even coming in to work last minute is a given. These are the heavier pieces of baggage; check what yours will entail. 


Are the job responsibilities and expectations a good fit for you? Transparent and clear-cut standards expected in your new role should be defined before you sign on for that job offer. The last thing you need is an unexpected role or duty that wasn’t a part of what you signed up forliterally. Some job offers or descriptions may have a vague task such as “additional responsibilities as needed.” Get clarification on this and ask the hiring manager to spell it out for you in writing.

Environment & Culture

According to the Harvard Business Review, one of the main reasons for employee turnover is its environment and culture. Suppose there is a disconnect between the company’s work ethics, culture, and goals, and its employees’ beliefs and values. In that case, there’s a higher chance for a turnover or resignation from employees due to this incompatibility. 

Before you say “yes” to the offer, take the time to dig deep into the company’s environment and work culture. While you may have grazed the topic during your initial research for your job interview, revisit it more deeply before committing to the position. Try reaching out to a current employee to see if you can inquire about what it’s like working with that company, over coffee. 

Lifestyle Changes

Consider what responsibilities accompany the salary, especially if that number is six figures. Most applicants will think about how much they can do with that much income; however, the more money you’re offered, the more work you are likely to have.

With that responsibility, do a quick run-through of your life now and where you see yourself in five years: adopting a dog, getting married, having a family, travelling abroad two to three times a year? 

One of the most flexible and freeing jobs is a career in data science and programming. Individuals who pursue careers in this field are generally happier and satisfied due to its excellent pay, flexibility, level of autonomy, and ability to have a pretty solid work-life balance. 

These are pretty relevant factors in overall job satisfaction. Take these into consideration before you accept a job offer. Consider whether the new role will drastically hinder your current or planned lifestyle. Are you ready to make over your current situation to cater to your new job? Or will your new job keep you from fulfilling your lifestyle goals? 

Perks & Benefits

An employee’s motivating factor and a key to job satisfaction and employee retention involves the perks and added benefits provided by the company. Holidays? Overtime pay? Health insurance? Does the company offer duty meals or an office pantry with free coffee? It may seem trivial, but perks, incentives, and benefits help boost work morale, increase job satisfaction, and enable you to save hundreds of dollars yearly from buying coffee at the local coffee shop. Yes, even as something as simple as free-flowing coffee at work is a welcome perk! 


With today’s unemployment rate at an all-time high in decades, another factor to consider is whether the job and company are stable. 

A career in finance, such as accountancy, is proven to be a stable career path regardless of the career trends or economic situation. According to the Bureau of Labor Statistics, this career path’s unemployment rate is only at 1.4% compared to the service industry at a whopping 12%. The latter statistic is directly connected to the current pandemic, which has heavily affected the service and tourism industry. 

It may be too late to evaluate whether the path you have chosen is stable if there’s a job offer on the table. Instead, probe into the company’s stability. By checking its employee turnover rate and average tenure, you can get a good idea of the organisation’s stability. 

In essence, before you accept the job offer, get clear on whether you are willing to put yourself through the job expectations and demands in exchange for the offer they have laid out for you. Try not to focus on the salary alone, but instead look at the overall working package for that specific organisation. If this doesn’t work out for you, you can maintain professional friends for referrals to other jobs.  

If the above is still unclear, and the job is still a “yes” for you, except for one or two factors that you need to mull over, you can always negotiate and prepare a counteroffer.

Google Voice Searches

You will find the answer to the following questions?

  • What Are They?
  • How Do They Influence Seo?
  • 4 Keys To Take Advantage Of Them.

Most Google searches now will be by voice.

In fact, you are already seeing the change. Surely you use it yourself: you go in the car and you need to find a parking space quickly. What do you do? Do you roll down the window, like before, and ask the first one to come in?

No. You ask your mobile. And your mobile tells you where you have to go to the park. That easy.

And that’s not all.

The growth of voice searches brings changes to the SEO of your website that you must know to know how to use them in your favor.

In this, we are going to explain:

  • What are voice searches (and their relationship with SEO)?
  • How to use them to your advantage to attract more organic traffic?

What are Google voice searches?

Let’s start at the beginning.

Since you know Google you have used it to search by typing a few words in the browser bar, right?

From this information, Google tracks the results that it considers most relevant to your search and shows them to you.

We all know that procedure.

Well, voice searches are essentially the same as traditional searches. What changes is the method you use to communicate with the search engine and make it understand what you want?

Voice search is a technology that allows us to search the internet orally asking our smartphone, tablet, PC, or smart speaker.

To communicate we need a virtual assistant. Today most devices have one. These are the main ones:

Siri: It was the first virtual assistant to be installed on an (Apple) smartphone, and it was introduced in 2011. There were already assistants for simple tasks, such as voice dialing or transcription. Siri went further, she could answer complex requests.

Cortana: It is Microsoft’s best in the field of voice assistants, but it seems that it is left behind, since it withdraws from Android and iOS, although it will still be available for Windows 10.

Google Assistant: it is the one you have on any Android smartphone and on the Google Home (smart speakers) that you can install at home to automate household tasks, among other features.

Alexa: Amazon has entered the field of virtual assistants with great force and it seems that it is taking the lead with Alexa and its smart Echo speakers.

Voice searches are increasingly integrated into our habits. The way we communicate with our devices and access information is already changing (and more will change).

Why understanding and taking advantage of this change is important?

Because a few years ago talking about voice recognition technologies could seem a long way off, but today they are already assimilated and it is expected that in the coming years they will have a spectacular development.

We are going to tell you in numbers. In the first four months of 2019, 42% of internet users used voice search at least once.

Almost half.

And 32% did it through their smartphone, which is by far the most widely used device. Why? Because this way of searching is:

  • Simple.
  • Comfortable.
  • Quick.
  • Effective.

Voice searches increase exponentially, year after year. It is a trend that must be followed closely because it will change the search habits of users.

Reasons to include voice search in your SEO strategy

As we were saying, voice searches increase with each passing day.

It is estimated that in a short time they will account for half of the total searches made on the internet. And you can’t stay on the sidelines. Because even if you have been optimizing your website for SEO for some time, voice searches work in a somewhat different way.

Look at this.

When you search in the browser Google shows you on the first page the 10 most relevant results.

Your SEO objective is to position your keyword to be on that podium of ten winners. The higher up, the better. In any case, appearing among those organic results is a good result and gives you possibilities to increase your traffic.

But what about voice searches? Imagine you are doing a search while you are walking or driving.

You can’t stop to analyze those ten results, so the wizard simplifies: it gives you only one.


Do you realize what that means?

There is a winner and everyone else loses. It changes the rules of the game by quite a bit. You have to aspire to that first position and for that, you need to adapt the SEO strategy.

What are Featured Snippets or zero position?

Google, above the organic results, places an outstanding result.

It is the one that considers that it best responds to the user’s search intention and offers it first. That is the Featured Snippet.

Being the first and above all others (without displacing them, that is why it is also called “the zero position”), it is the one that takes the prize: it monopolizes clicks.

This is what the voice assistant offers you.

Do you realize how Google is moving towards choosing a single result?

You may wonder what you have to do to appear in that privileged place and take all the clicks, but that’s another matter. The important thing is that by now you have already realized that you have to adapt your SEO strategy to voice searches.

4 keys to rank better in voice searches

Falling behind is unthinkable, so the sooner you start optimizing to try and position yourself in voice searches, the better.

Here are some hints so you know where to start.

#1. The user’s search intention and the importance of long tails
First of all, you have to keep in mind that when we speak to a virtual assistant we do it as if it were a natural “conversation”.

That is, with short and colloquial phrases. It is a comfortable way to communicate. For example:

In the browser, you would write an “Italian restaurant in my city”.

However, you ask your voice assistant ” Where can I eat pizza near here?”

In fact, most searches are basic questions that start with:

  • Than
  • Who
  • How
  • Where
  • When

Why are we telling you all this? Because you have to know what are the most popular questions among users or clients in your sector.

And that’s why, in addition to keywords, you are interested in looking closely at long tails.

The tails long “normal” are keywords longer, but in this case, the tails long become “long keyword phrases” that sound much more natural in conversation. In addition, they provide guidance on the user’s search intention.

If a user types the keyword “chocolate muffins” it does not give many clues about their search intention. What exactly do you want to know?

Instead, these long tails do give clues about the search intention:

  • Where to buy chocolate muffins around here?
  • What are chocolate muffins?
  • Easy Chocolate Muffin Recipe?
  • How many calories are in chocolate muffins?

And they are formulated in the type of conversational language used in voice searches.

Therefore, your SEO strategy for voice searches has to analyze very well the user’s search intention and pay attention to long tails to include them.

#2. Optimize your content

In the previous point, we explained to you that the users of the voice search usually ask many very simple questions and with natural language.

Well, try to make your content answer those questions in a simple way and also with natural language. That way you will be facilitating the task to Google and it will “read” you better.

A good idea is to improve the FAQ. An FAQ page is ideal when answering all those questions that start with “what, who, where, how, etc”.

And it’s also a good place to include all long tails that match the user’s search intent.

#3. Pay attention to local SEO

Many voice searches are done on the go: walking down the street, driving, while shopping at the supermarket.

And also many of them have to do with local searches. Using the “near me” so that the results are tailored to the user’s location.

Therefore, it is a great occasion for small businesses. We give you 2 ideas that can help you improve local SEO:

Create your business file in Google My Business: it is focused on local businesses and allows you to interact with customers. It facilitates searches on Google and Google Maps because it unifies the information about your business in one place.

Strengthen your location information throughout your On-Page strategy: include keywords with local references that could be used by someone who is currently there.

If you have a physical business, you should use these tricks.

#4. The loading speed of your website

We already know that the loading speed of your website or e-commerce is always an important SEO factor.

But also, in the case of voice searches you have to take this into account:

The pages with the highest loading speed are the ones Google prefers.

Look at the conclusions of this study that has analyzed the results of voice searches on Google:

  • The average loading time of a web page is 8.80 seconds.
  • Google search results for voice search have an average load time of 4.60 seconds.

Upload speed is an important parameter to rank. Therefore one of the priorities is to optimize the page so that it is as fast as possible.

Are you going to take advantage of voice searches in Google to improve your SEO?
You have already seen what voice searches are and how important it is to adapt your SEO strategy to take advantage of its possibilities, especially to make new clients for your e-commerce in local searches.

Why Laravel Is The Top PHP Framework In 2020-2021

Numerous PHP-frameworks are accessible to use as open-source and free. Be that as it may, at whatever point we talk about Laravel, then the issue is unique. Try not to stress. It is likewise open-source and free PHP structure; however, it came in presence as the top and a propelled contender to the CodeIgniter system.

It is furnished with numerous highlights; for example, worked in help for client authentication and authorization. CodeIgniter missed these highlights. That is the reason the web advancement process utilizing CodeIgniter was very hard.

The expansion of the above highlights expanded the ubiquity and distinction of the Laravel structure. Numerous Laravel development companies engineers as their significant component for creating web applications and believe it is the best and most prestigious PHP structure.

Engineers likewise use Bootstrap Laravel formats while they grow large and complex applications. Numerous different highlights make Laravel the best PHP system in 2020.

We take an itemized conversation on the highlights and rule of the Laravel PHP system in web advancement:

Application structure

About the application structure in Laravel, it accompanies a default application structure. Its application structure is straightforward to use, thus giving high convenience to begin little or huge applications. With this component, designers can modify the application according to the proprietor requests.

Multiple File Storage System

Laravel is in build with various storage systems like cloud, Amazon, and other Exchanging between these profoundly included, and in vogue distributed storage systems will be a not too bad and simple errand because the API utilized for every one of these systems is the equivalent.

A standout amongst other things like this will be the designer will be permitted to use all these three distributed storage systems just in a single application. It will allow engineers to rapidly and effectively serve these files from various areas with no issue.

MVC Architecture Support

Laravel Authentication Library is outfitted with a wide scope of cutting edge highlights. A portion of different highlights incorporates checking dynamic clients, cross-site insurance and REquest Forgery encryption, Bcrypt hashing, and secret key reset.


Laravel offers restriction benefits that are useful to the engineers in a way to recover strings of a few dialects. Along these lines, the web application will bolster different dialects without any problem. It is beyond the realm of imagination with various frameworks, so it makes Laravel a worldwide marvel.


Pagination is a run of the mill task in web advancement; however, Laravel makes it simpler at the initial step. It causes designers to make clever connections for any site created on the HTML and current page. Moreover, the connections made by designers utilizing pagination in Laravel will perfect with Bootstrap CSS structure.

Sharp edge Template Engine

One of the intriguing realities about Laravel is that it gives an in-manufactured layout motor named Blade. The powerful and smooth Blade templating motor necessarily accompanied Laravel 5.1. Laravel accompanies a first anyway still strong templating engine which isn’t accessible in other PHP frameworks.

It helps engineers from using the understandable code in the views. Also, the cutting edge views then effortlessly take care of into simple PHP code and are before revamped they are stored.

In a couple of conditions, altering or erasing an announcement appears to be an extreme errand while dealing with unpredictable and enormous undertakings. Be that as it may, Blade in Laravel encourages designers to expel or change the announcement with no issue handily.

Steering System

Laravel encourages designers to use a directing framework that is exceptionally helpful and straightforward. They require building up an index for the URI and afterward create and execute appropriate connects to the named courses.

The primary advantage is that while making the code, it puts the URIs depended on connections to the particular links and paths and updates them if the course change.


There are just a couple of frameworks that realize that making authentication is straightforward and quick. Like this, everything has been designed and included as of now for the web engineers for the most part.

The arrangement files comprise every single extraordinary archive that is basic for dealing with the elements of authentication services.

Programming Task Management and arrangement

In each web advancement, the process task the executives and setup is a fundamental factor that ought to be considered by each engineer top to bottom. It is likewise a necessary errand to be done on schedule. It may be sending some other errands or an email, clearing the database, overseeing undertakings efficiently consistently assume a significant job.

Try not to stress the platitude possibly commonplace, yet usage isn’t as Laravel is here with an order scheduler.

While utilizing the order scheduler, just the code passage will be included your server. Corn calls this scheduler over and over.

After the execution of the order, Laravel assesses the booked errand and run all the pending assignments. As such, Laravel offers ease in planning and dealing with the undertakings.


It is challenging to state if any web application is secure and ensured. With the Laravel PHP structure can give the top security to web applications as the passwords will never get spared inside the system as the understandable content. This is the principle reason Laravel uses the hashed secret phrase for security.

Laravel likewise gives the best counteraction to your web applications from infusion assaults. It utilizes SQL articulations to decrease the opportunity for genuine dangers.

Laravel offers numerous security features that include ensuring courses, encryption, HTTP essential authentication, and so forth.

Programmed Package Discovery

Programmed Package Discovery in Laravel discovers which bundles are wanted by clients to introduce. There is no compelling reason to set up any examination.

It is anything but challenging to impair this element, and engineers can do it with no issue. This component is likewise the purpose behind the ubiquity of Laravel.
