I don't know about PyPy.js specifically, but most systems like this provide a virtual filesystem that maps back to things like indexedDB and localstorage which are browser APIs.

There is no way that pypy.js is able to access local files on your machine outside of the browser sandbox.

I bet there's a few cheeky hackers around the world who may disagree with that statement. Always assume it's broken.

No, not in this case. It's running in JS land in the browser so any exploits to break out of the browser sandbox using this could be done simpler with raw JS.
