JSCocoa 1.0, write Cocoa apps in Javascript

Do you want to write Cocoa applications, but happen to be handier with Javascript than with Objective-C? JSCocoa to the rescue! Similar in concept to RubyCocoa, JSCocoa provides a bridge between Webkit's JavascriptCore and Cocoa, allowing you to call C and Objective-C code, as well as build Javascript classes which inherit from Objective-C classes.

Visit the Google Code page for a quickstart and some syntax explanations. JSCocoa is open source and available for subversion checkout or direct download.
