It supports all the modern browsers such as IE6+, FF, Chrome, Safari 6+, Opera 12+, etc. Ext JS was originally built as an add-on library extension of YUI in 2007. It is mainly used to develop desktop applications, however, the last version of Ext JS 6 is a single platform, which can be utilized for both desktop and mobile application without having the different code for the different platform. Ext JS is also compatible with jQuery and Prototype. It is based on MVC/MVVM architecture hence the code is highly readable. Ext JS includes a set of form controls based on the graphical user interface for use in web applications: text field and text area input controls, date fields, numeric fields, list box, HTML editor control, sliders, and many others. Custom Themes Ext JS widgets are available in several out-of-the-box themes that are compatible across platforms.
