What is jQuery?

JQuery is a fast, small, cross-platform and feature-rich JavaScript library to handle client side development.

JQuery also simplifies a lot of the complicated things from JavaScript, like AJAX calls and DOM manipulation.

The jQuery library contains the following features:


1.     HTML/DOM manipulation

2.     CSS manipulation

3.     HTML event methods

4.     Effects and animations

5.     AJAX

6.     Utilities

There are two versions of jQuery available for downloading:

Production version - this is for your live website because it has been minified and compressed

Development version - this is for testing and development (uncompressed and readable code)
