CodeJS
Class / Object Development Environment for JavaScript
CodeJS is a dialect of JavaScript that will make it natural for AS3 programmers to transition into Web standards.

Code.js is a compact js library that powers another library called FaseJS, a collection of classes familiar to Flash developers for creating and manipulating a DisplayList and handling Events within the DOM.
