What is JavaScript?

JavaScript is a client side scripting language and it is used in a browser to make interface interaction possible to control. It is an interpreted language. Brendan Eich made the first JavaScript engine for Netscape Navigator web browser. The code was named “Spider Monkey” and it was developed in C language.

JavaScript was originally called as “Mocha” then it was renamed to “Live Script”. Finally after the license agreement between Sun and Netscape it was renamed to JavaScript.

JavaScript is commonly used for client-side validation, showing pop-up, user onclick etc. and for controlling the document content displayed to the user.

What is Jquery?

Jquery is a JavaScript library and it is made using JavaScript. It was first released in 2006 and it was made by “John Resign”. JQuery is a small, fast and rich feature library. It is widely used for AJAX requests, DOM element traversal, event handling and cross browsers JavaScript functions.

Head To Head Comparison Between JavaScript vs JQuery

It is a programming language. It is JavaScript library.
It is written in C. It is an interpreted language. It is written in JavaScript as it is a JavaScript Library.
You have to write your own functions for almost everything you want. JQuery has built-in functions which can be used to get desired results.
You have to control cross-browser issues and have to write a cross-platform code on your own. JQuery is a cross-browser JavaScript library. The code written in JQuery will work same in all the browsers.
Using JavaScript you have to write every single line of your code of your functions on your own so the code will grow if you need more functionality. In JQuery you can use JQuery built-in functions like hide(), show(), toggle() etc. and you can get your desired result in a few lines compared to JavaScript.
JavaScript is faster in accessing DOM (document object model.) elements as it has no overhead which JQuery has. JQuery is slow comparing it to JavaScript but not very slow as with modern browsers and fast computers we have now. We recommend you not use JQuery if you just want to show or hide contents etc.
It is used on client side as it runs in a browser. JQuery is also commonly used on Client Side as it is a JavaScript library.
JavaScript can be turned off by user in the browser. JQuery don’t work if JavaScript is turned off.
<script> </script> HTML tags are used to write any JavaScript code in an HTML page. Or you can import any JavaScript file using these tags. JQuery is also written in <script></script> HTML tags but you first need to import JQuery file in an HTML document. It can be downloaded or you can use the Jquery CDN code.
No special characters are used in writing JavaScript code. $ is most commonly used in Jquery By default you can use “$” as a shortcut for “jQuery” So, using $(selector) or jQuery(selector) is the same.
JavaScript don’t have documentation like Jquery. Jquery has a comprehensive documentation and code examples to find help to understand and begin programming even to beginners.
You have to write a lot of code for an AJAX request. Jquery develops Ajax templates with ease less code than JavaScript.

Now lets us see JavaScript vs Jquery code example. Below is the code for hiding a div with id=”htc”.

Jquery code of hiding <div id=”htc”></div>

$('#htc ').slideUp();
$('#htc ').fadeOut();

Here is the JavaScript code of hiding <div id=”htc”></div>

document.getElementById("htc").style.display = 'none';
document.getElementById("htc").style.visibility = 'hidden';
