jQuery - Write Less, Do More.

[jay]

jQuery is a fast, concise, JavaScript Library that simplifies how you traverse HTML documents, handle events, perform animations, and add Ajax interactions to your web pages. jQuery is designed to change the way that you write JavaScript.

It is not a huge, bloated framework promising the best in AJAX - nor is it just a set of needlessly complex enhancements - jQuery is designed to change the way that you write Javascript.

jQuery achieves this goal by taking common, repetitive, tasks, stripping out all the unnecessary markup, and leaving them short, smart and understandable.
