5 Rich Javascript Framework

ExtJS

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. Ext JS 4 also brings an entirely new data package that enables developers to use a model-view-controller architecture when building their app. The new MVC enables apps to leverage features like Infinite Scrolling a Grid to build an entirely new level of interactivity in to web apps.

Cappuccino

Cappuccino is an open source application framework for developing applications that look and feel like the desktop software users are familiar with.

Cappuccino is built on top of standard web technologies like JavaScript, and it implements most of the familiar APIs from GNUstep and Apple’s Cocoa frameworks. When you program in Cappuccino, you don’t need to concern yourself with the complexities of traditional web technologies like HTML, CSS, or even the DOM. The unpleasantries of building complex cross browser applications are abstracted away for you.

Cappuccino was implemented using a new programming language called Objective-J, which is modelled after Objective-C and built entirely on top of JavaScript. Programs written in Objective-J are interpreted in the client, so no compilation or plugins are required. Objective-J is released alongside Cappuccino in this project and under the LGPL.
