Flutterby™! : js2js

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.

Or, how to over-complexify writing "cp" in a scripting language....

The sad thing is that I went and dug through the code a bit, because a super-strict "lint" like tool that helped clean up some of the worst bits of JavaScript would actually be a super handy tool.
