What is Sencha Ext JS?
Sencha Ext JS is the leading standard for business-grade web application development. With over 100 examples, 1000 APIs, hundreds of components, a full documentation suite and built in themes, Ext JS provides the tools necessary to build robust desktop applications. Ext JS also brings a rich data package that allows developers to use a model-view-controller (MVC) architecture when building their app. The MVC leverages features like Big Data Grids enabling an entirely new level of interactivity in web apps.
Modern App Framework
Ext JS 4 is a major step forward for web frameworks. Building on Ext JS 3.3, our latest release adds over 350 new APIs, 50 new classes, and 65% more documentation. An entirely new data package equips developers to leverage features like Infinite Grid Scrolling to build an entirely new level of interactivity to web apps.
MVC Application Architecture
Ext JS 4 brings a whole new way to build client applications, by introducing the popular model-view-controller pattern to Ext JS. By allowing the separation of data management, logic and interface elements, Ext JS 4 makes it easier for even large development teams to work independently without worrying about stepping on each other's toes. Ext JS 4 ships with a helpful MVC guide to get started.
Cross Platform Browser Compatibility
Ext JS 4 lets developers deliver on an incredible variety of browsers and on more operating systems using the same code — over ten years of browsers in one release. On modern browsers, Ext JS 4 utilizes HTML5 features and falls back to alternatives on older browsers. Whether you’re using Ext JS’ built-in UI components, using the Charting package, or theming your application, Ext JS 4 makes it easy to build an app that gives you the power of the web regardless of what browser your customer uses.
Ext JS supports all major web browsers including:
Internet Explorer 6+
Firefox 3.6+ (PC, Mac)
Opera 11+ (PC, Mac)
