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
|
