Project Summary
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.
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.
"You start with 10 lines of jQuery that would have been 20 lines of tedious DOM JavaScript. By the time you are done it's down to two or three lines and it couldn't get any shorter unless it read your mind." - Dave Methvin
