What is jQuery?

jQuery is a lightweight, "write less, do more", JavaScript library.
The purpose of jQuery is to make it much easier to use JavaScript on your website.

jQuery takes a lot of common tasks that require many
lines of JavaScript code to accomplish, and wraps them
into methods that you can call with a single line of code.
jQuery also simplifies a lot of the complicated things
from JavaScript, like AJAX calls and DOM manipulation.
The jQuery library contains the following features:
HTML/DOM manipulation
CSS manipulation
HTML event methods
Effects and animations
AJAX
Utilities
