Running

The easiest way is to use parcel

parcel index.html

Then you can use _eval in the developper console. Example

_eval("let inc = fn(x: int) => x + 1 in inc(100)");

More features

I'll be adding occasionnally examples for supporting more features. The
examples will be in separate branches.

• boolean types && if construct, also has more operations && priority/associativity (example)

• record types (example)

• type inference (using Algorithm W) (example)

• subtyping (example)
