Rust compilation is also almost instant, if you have a relatively small project.

It's only when you get very large projects that compilation time becomes a problem.

If typescript compilation speed wasn't a problem, then why would Microsoft put resources into rewriting the tyescript compiler in Go to make it faster[1]?

Good to know, my $DAYJOB project unfortunately isn’t as well informed and we have to use esbuild just to survive.
