I've hacked on this interpreter some, it's pretty nice to read! It implements a very limited subset of JavaScript, something like ES3. I'd be really interested to hear about other similar implementations of JavaScript in JavaScript. I stopped working on https://github.com/thomasballinger/hotswapping-js-interp#js-interpreter-with-hot-swappable-functions https://github.com/thomasballinger/hotswapping-js-interp#js-... partially because copying the state of the interpreter was relatively slow. I'd be interested in implementations that would handle this better by using a more bytecode-like VM or immutable data structures.
