Js2js: A revolutionary open-source compiler from JavaScript to JavaScript

The footer says that if you want a real "Javascript to Javascript interpreter", to see js.js[0], which is a JS interpreter written JS; where the satirical js2js is a JS-to-JS compiler, something different. If you want a real JS to JS compiler, see Google's "Closure Compiler"[1].

In the intervening years we've accumulated more js2js compilers. IMO the best one is 6to5 [1].

Here's the real nut-meat

    Js2JsCompiler.prototype.compileCode = function(code) {
        return code; // as we need to compile javascript to javascript, we do nothing here :)
    };

Very helpfully commented!

It can also decompile JS back to JS, cool!

Can you generate a map file for in-browser debugging?

What is up with all these troll projects recently?

IKR?

Are you talking about:

(a) the obvious trolls, where the fact that it's a diversion is visible quickly from the text/code, or (b) the non-obvious trolls, where a significant chunk of the industry enthusiastically adopts something with marginal benefits not only as a tool but an aspirational standard for 3-5 years before judging it either a dead-end or inferior to the new hotness?

Both!

Funny!
