Cocoa-Like JavaScript Framework Announced

TwilightSentry writes "Ars Technica reports that a group of developers has created an Objective-C-like extension to JavaScript along with a class library mirroring Cocoa. They've used these to release an impressive demo app called 280 Slides. The article notes, 'Whereas SproutCore seeks to "embrace the platform" by giving a Cocoa-like development model for developers already using HTML, CSS, and JavaScript to make a web app, Cappuccino and Objective-J take an entirely different approach. "Since Cappuccino runs entirely on the client, at run time, we're never actually generating HTML or CSS," says Boucher. "When you build an application in Cappuccino, you don't need to ever deal with HTML or CSS. All of your interface is designed in Objective-J and Cappuccino. Cappuccino focuses on application architecture more than anything else, like building applications that know how to save and open documents, or copy and paste. We also built a powerful graphics engine into Cappuccino, so you can make rich applications like 280 Slides."' The developers plan to release the framework and preprocessor as open source. No mention is made of a specific license."
