> Javascript has a quite different use-case audience than Rust.
Eh. That sounds like a "just so" explanation to me. Linus Torvalds doesn't work on the rust compiler.
I think I could make much more convincing arguments that javascript should move slower than rust - given there's so many large language runtime projects. (V8, Safari, Javascript, Node, Deno, Bun, etc etc). But evidently, that isn't the case.
I'm open to the reason for rust's slow development being that the language developers want the language to move slowly. Thats fine. But, I personally don't want that. I've been waiting for generators to ship for 7 years. Or TAIT to appear - again, for years. I'd much rather rust to move faster.
Of course I attribute all of this to the process & team which makes these decisions. What else is there? What else has any affect on the development of rust?
