This project is an attempted rewrite of Bebbington's js.rs. Most of the Rust code has been rewritten from scratch.
#### WASM
This interpreter can be exposed to javascript!
You can build the example locally with:
```
$ yarn install
$ yarn serve
```
In the console you can use `window.evaluate` to pass JavaScript in
