JavaScript is a language.
Jquery is a framework built with JavaScript for helping you to use that language

Hi,

javascript is interpreter and Jquery is collection of javascript features

Jquery is simply javascript Library.

it developed for just reusability of code.

for e.g:

without JQuery we've to write below line for accessing element in document.

document.getElementByID("elementID").property

But with Jquery

we just write

$("#elementID").property

this is just example if you go for synchronous requests we've to write

almost 10 lines with Jquery.

If we use Jquery means its just in one line

$.get("pagename.aspx",{},function(data){});

I hope you understood What I said

All the Best
