It absolutely was. All it takes is a quick look around other language ecosystems and JS itself.

Rust is an excellent language for embedding in other languages And underpinning developer tools.

That said, someday the new typescript binary will compile to WebAssembly, and it won’t matter much anyway.

There is that opposite approach, yes. Add low-level control to TypeScript and get it to compile to WebAssembly, then the compiler itself can be fast as well.

I suspect they wanted the compiler speed more than they wanted a WASM target, though.
