If you think of typescript as "tooling" that makes sense.

But if you think of it as compiler, or transpiler, not so much. Python, Ruby etc "compilers" (runtimes, really) aren't written in Python or Ruby. Or rather, there are alternatives around, but they aren't the fastest nor the best. Such "tools" are built in C. As are compilers for C++, Rust or most languages really.

I understand your point. Compilers and interpreters are traditionally written in C/C++, but we don't have to do the same than before.
