Jquery is a cross-browser JavaScript library that is developed to simplify the client-side scripting of HTML.It was released in january 2006 at BarCamp NYC by John Resig. JQuery is free, easy to use and open source scripting language. JQuery's syntax are easy. Using Jquery we can select DOM elements, create animations, handle different types of events, and develop ajax based applications.
JQuery also provides facilities for developers to create own plugins on top of the JavaScript library. Using these capabilities, developers are able to create high level interaction and animation, advanced effects, theme-able widgets. This contributes to the formation of interactive and dynamic web pages.
