# A small bytecode VM in javascript

This is a pretty simple bytecode VM implemented in javascript. I have also

written a little language to go with it and to try stuff out, though the

semantics of that language are mostly defined by the abstract syntax tree, and

the VM can be made to work very differently.

## How to

1. Compile the grammar by running `make`

1. Check out the sweet railroad diagrams generated at `grammar/grammar.html`

1. Write a cool script in a file (good luck figuring out how the language works)

1. Run it `npm run start -- mycoolscript.jsbcvm`

Here's a snippet of the language:

```js

function multiplier(a) {

  return b => a * b;

}

var times2 = multiplier(2);

print(times2(4));

```

## Next steps

- other datatypes (hashmap)

- modules

    - There is currently support for `include`-style imports, but that kinda

      sucks
