jangaroo: write actionscript, run javascript

jangaroo provides an actionscript to javascript compiler.

 

from the site:

So far, JavaScript projects had to rely on proprietary runtime extensions to conveniently build classes, inherit from a superclass, do a super call and so on. There was no tool support for these extensions. ActionScript 3 can do better, but it is not available in every environment, or only through plug-ins.

We carefully selected ActionScript 3 language features that JavaScript 1.x developers need most desperately for Object-Oriented Programming "in the large" to form the Jangaroo language. Because the Jangaroo language is a subset of AS3, it profits from third party tool support, like Flex's documentation tool asdoc or JetBrains' fantastic IDE IntelliJ IDEA.
