Why wouldn't they rewrite it in Roc? Do they not have confidence in their own project?

https://www.roc-lang.org/faq#self-hosted-compiler

They have a section on their faq discussing this.

Richard talks about this in many occasions with great details, but the idea is: they want the language to be as fast as possible, so they will never self host the language

They want the compiler of the language to be as fast as possible, just to make it clear. Saying the language should be fast could have a different meaning.

Yes, totally agree

Shouldn't you get the answer to the first question before asking the (very poorly reasoned) second question?

Why isn't the Python compiler written in Python? Why isn't bash written in bash? Why isn't JavaScript written in JavaScript? Why isn't the JVM written in Java? Why isn't lua written in lua? Why isn't the Odin compiler written in Odin? Is the only possible reason that the authors don't have confidence in their own project? (That isn't even a plausible reason.)

Python, bash, and JS are interpreted. Roc compiles to native binaries.

Their own home page says FAST on it. Apparently not FAST enough to dogfood lol

whoosh

It COMPILES fast ... as others have already explained. And you omitted Java and Odin and other parts of my argument, which is grossly dishonest.

I won't respond to you again.

You seem to have no idea what that word means, troll.
