We’ve had a library for generating JS bindings for Rust code for decades?

[slimsag]

Agreed, I doubt it's been a decade.. though maybe close-ish

wasm-bindgen does something similar though, right?

It does, but wasm-bindgen is currently missing some features that I personally think are necessary for widespread adoption. Things like being able to have a `Vec<T>` without venturing into type unsafe land and JSON.
