JQuery | Difference between JavaScript and JQuery 

Javascript is a client-side scripting language whereas jQuery is a library (or framework) built with JavaScript.



Javascript JQuery 
javascript is a dynamic and interpreted client-side scripting language Jquery is a library (or framework) built with JavaScript
Required more line of code with JavaScript Required less line of code with Jquery
Need to write extra lines of code to meet the cross-browser compatibility. JQuery has an inbuilt feature of cross-browser compatibility.
Pure JavaScript can be faster for DOM selection/manipulation than JQuery as JavaScript is directly processed by the browser. JQuery is also fast but it required to convert the JQuery code into javascript to make it run in a browser as it is built on JavaScript.
The browser itself understands and supports JavaScript. It is required to include the jQuery library URL in the header of the page.
