Ext JS

Ext JS is a JavaScript application framework for building interactive cross-platform web applications using techniques such as Ajax, DHTML and DOM scripting. It can be used as a simple component framework (for example, to create dynamic grids on otherwise static pages) but also as a full framework for building single-page applications (SPAs). Originally built as an add-on library extension of YUI by Jack Slocum on April 15, 2007, Ext JS has had no dependencies on external libraries beginning with version 1.1. Nowadays, Ext JS can be used both as a single script (with all classes and components in one file) or by building the application with the Sencha CMD.
