What is jQuery?

jQuery is a JavaScript library that simplifies many complex actions, such as DOM manipulation and web service calls, through JSON or AJAX. By using jQuery, you can minimize the amount of code you write, reduce development cycles, and simplify maintenance of your application.

It's important to remember that since jQuery is built on top of JavaScript, the code that will or will not work depends on a platform's support of JavaScript. If you have a desktop web application already implemented with jQuery, there is a very good chance that newer platforms will simply run your code.

You can use jQuery under the GPL or MIT license for use in commercial applications.
