Sencha Ext JS 4 is the industry’s most powerful application development platform and it possesses an advanced MVC architecture, plugin free charting and modern UI widgets. It provides unparalleled cross-browser compatibility enabling us to develop incredible web applications for any browser.
Basically it is a major step forward for web application development. It also brings an entirely new data package that enables developers to use a model-view-controller architecture when building the applications. The new MVC enables applications to leverage features like infinite scrolling a grid to build an entirely new level of interactivity into web applications.
**Sencha Ext JS 4 comprises of the following features:**
- Rich, modern UI widgets
- Clean component model
- Cross platform browser compatibility
- Plugin-free charting
- Modern application framework

- Sencha cmd
At e-Zest, we use Sencha Cmd which is the cornerstone to build our Sencha applications. From scaffolding a new project, to minifying and deploying our application to production, Sencha Cmd provides a full set of lifecycle management features to compliment our Sencha project. With a rich command line syntax and Ant integration, Cmd is perfect to integrate into our enterprise build environment or use standalone for our applications.
Ext JS offers an extraordinary range of user interface widgets. High performance scalable grids, trees, menus, and more. Our developers use Sencha EXT JS 4 because of its core strength that is component design. We can easily extend the default components to meet our needs, and extensions that get encapsulated within those components. As a result, our development teams can create even the largest applications without stepping on each other’s code.
Sencha Ext JS 4 lets e-Zest’s developers deliver on an incredible variety of browsers and on more operating systems using the same code. Whether we use Sencha Ext JS 4’s built-in UI components, use the new Charting package, or theme our application, it makes easy to build an application that gives us the power of the web regardless of what browser our customer uses.
With Sencha ext JS 4 framework our developers have experienced that there are no plugin problems. Leveraging SVG and VML, the Sencha Ext JS 4 charting package lets our developers to design and program their graphs once for all browsers.
At e-Zest it brings a whole new way to build client applications, by introducing the popular model-view-controller pattern. By allowing the separation of data management, logic and interface elements, the framework makes it easier for even our large development team to work independently.
