Or just write faster JS using it's lower-level language features. Nothing about whatever collection of build tools the JS ecosystem uses "requires" rust/zig/c++/go for performance. It's a closed text transform problem.

The native languages are easier to get decent performance for sure but, braking the entire ecosystem and a generation of future contributors, for what should realistically be single or low double digit percent gains is not worth it.
