Have you ever considered AssemblyScript?

[matthew-dean]

One of the things that's true about Chevrotain is no matter how blazing fast it is for a JavaScript parser, it still has a theoretical performance limit imposed by JavaScript itself.

I'm wondering if you've ever considered rebuilding in something like AssemblyScript? An implementer could, in theory, implement a parser in TypeScript / JavaScript OR AssemblyScript (I think?), and compile the parser to WASM for some amazing speed gains (in theory).

However, I don't know all of the internals of Chevrotain, and it's possible there are some JS features that are not yet available there. But I was just curious.

I won't be surprised if some internals cannot be converted, there is quite a bit of dynamic behavior under the hood, e.g:

Regardless of that, if I understand correctly:
WASM binaries need special interop to be used in JavaScript code
and this seems mutually exclusive with a publishing a library with many APIs to be used directly in the consumer's JS code, e.g:
