It seems you're oblivious to the fact that projects such as swc[1] exist, and have been adopted by projects such as deno.

I'm not familiar with Elixir nor am I in a googling mood. Nevertheless that was an awfully short list. Why is that?

swc only does transpilation, it does not support TypeScript's type-checking which is its main feature.
