Does TypeScript emit machine code? OCaml gives you this option, if you need it.

Well, TS transpiles to JS which then runs on Node, aka V8, a native JIT compiler. So yes, I guess?

Kind of, given that V8 performance is never going to be as good as AOT compiled language, and JIT needs warmup time.

It is no accident that famous JavaScript tools keep being rewritten into C++, Dart, Go and Rust.

But they say "we use ocaml [because it has types]" not "[because it can emit machine code]"

I would go for Rust if I wanted machine code
