Go is exceptionally fast for a transpiler. Esbuild is a great example.. Rust would offer any significant gains vs adoption for support.

Unless, of course, you are not working on a greenfield project and instead are porting an existing compiler from Typescript, in which case Go is the language you would choose as it is the language that most closely resembles Typescript, allowing ease of bulk conversion by script. The same reason why it was chosen for Typescript.

I read that response and I agree entirely! Porting Js to Rust isn’t feasible. I love Rust but it’s good to know your constraints.
