"no transpiled language could ever succeed".... TypeScript.

• orthoxerox 4y ago
  TypeScript doesn't introduce new runtime semantics in practice, in 99% of the cases the generated JS is your TS code with types erased. There're no magic keywords that expand into pages of generated JS.

    They implemented the `x.y?.z` syntax pretty long before JS did, so that was at least transpiled for a while. I'll bet there are more features like that.
