I see.

I realize that work on project has just begun :)

44 KB - that's not bad!

Some time ago, I was interested in translation to JS, but I rather 
thought about binary translation, like in http://bellard.org/jslinux/. 
There's similar "emscripten" project which translates LLVM bytecode to 
JS: https://github.com/kripken/emscripten. And there's also commercial 
Morfik: http://en.wikipedia.org/wiki/Morfik. Perhaps you might find 
these links useful, if you don't know them already.
