Twostroke is a Javascript implementation written in pure Ruby. It currently consists of:

  • A parser (which works, but is in need of an overhaul)
  • Two compilers:
    • One that targets Javascript, perfect for obfuscation
    • And another that targets TSASM - Twostroke's internal bytecode format
  • A VM that runs TSASM bytecode
  • A minimal Javascript standard library implementation (also in need of some love)
  • A test suite containing:
    • Some tests written for Twostroke
    • Underscore.js's complete test suite (minus the cases relying on the DOM)

Why use Twostroke?

It's cool:


It actually works:

yep, that's unmodified underscore.js:

tests lol
