Ext JS is based on MVC/ MVVM architecture and its latest version is Ext JS 6 which is a single platform used for developing both desktop and mobile applications without having different code for each platform.
Ext JS first version 1.0 was developed by Jack Slocum in 2006 with a set of utility classes and an extension of YUI. Therefore, he named the library as YUI-ext.
Ext JS version 2.0 was released in 2007 with new API documentation for desktop Application with limited features. This version is not backward compatible with previous version of Ext JS.
Ext JS version 3.0 was released in 2009 with some added features like chart and list view but at the cost of speed. This version is backward compatible with version 2.0.
Later when Ext JS 3 was released, developers of Ext JS faced major challenge of ramping up the speed. Ext JS version 4.0 was released in 2011 to ramp up the speed. It had a fully revised structure with MVC architecture to speed up the application.
Ext JS version 5.0 was released in 2014 with major change like changing MVC architecture to MVVM architecture. It includes the ability in building desktop applications on touch-enabled devices, two-way data binding, responsive layouts and many more features.
