The Next Big Thing in JavaScript Evolution

js2js is a revolutionary open-source compiler from JavaScript to JavaScript

JavaScript is the new Assembly. There are dozens of tools that compile some programming language to JavaScript. You can do it with C++, Java, C#, Python, Scala or Ruby. But there's one language that remains to be covered for JavaScript to dominate the world: JavaScript.

We did it. Meet js2js, a revolutionary compiler that transforms JavaScript directly to JavaScript!
