Recently, I’ve been working on ExtJS framework which is made by Sencha. This framework is actually javascript framework built for developing rich user interfce web applications.

While developing a complex dynamic web applications or web sites, we often needs dynamic UI components such as grids, tree structures, tabs and other things which are quite difficult to make on core css/javascript. Although jquery offers you several things, but ExtJS provide a flexible and easiest, dynamic way to apply such solutions.

ExtJS offers full documented help and API index where developer will find it quite much easier to start any ExtJS application. Almost all of the UI components supports JSON data call from your favourite server side script on your web server.

Currently ExtJS ver. 4.02 is available for download.
