PyPy. Compiled into JavaScript. JIT-compiling to JavaScript at runtime. Because why not.
This is a very-much-in-flux collection of supporting scripts and infrastructure for an experimental emscripten/asmjs backend for PyPy. You can read more about the project (and try it out live!) here:
If you just want to use a pre-compiled PyPy.js interpreter, please download a release bundle from the above website and follow the instructions in the included README.
If you're like to work on the PyPy.js code itself, please see the details in CONTRIBUTING.rst.
