JQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development. jQuery is designed to change the way that you write JavaScript.

What is jQuery?

This is a small cross-browser JavaScript library created to simplify the client-side scripting of HTML. Jquerry was released in early 2006 at BarCamp NYC and until then it became the most popular JavaScript library in use. jQuery was developed to change the way programmer write JavaScript using a combination of versatility and extensibility. This fast, small rich-featured JavaScript library is able to make things much simpler with an intuitive API that works over multiple browsers.

This is an open source software, dual-licensed under the MIT License and the GNU General Public License. Now it is easier to navigate a document, select DOM elements, do animations, handle events and create Ajax apps. Thanks to jQuery developers are able to create plugins on top pf the JavaScript library, develop abstractions for low-level interaction and animation, advanced effects and high-level, theme-able widgets. Powerful and dynamic websites now can be created.
