I think self-hosting is just a little over-rated for languages. It's good that Rust and C++ are self-hosting, you'd expect those to be languages you can write a compiler in.

But Lua and JavaScript satisfy their own niche just fine without having popular runtimes written in themselves.

Most languages don't aspire to be so conceptually-complete that they insist on being bootstrapped. Which is fine, I make my living with them.

Those that do, however, are immensely beautiful and there is more to be learned from them.

There are a few JS interpreters written in JS, don't know about Lua.
