> I just don’t think we’ve exhausted all the possibilities of making JavaScript tools faster
Rewriting in more performant languages spares you from the pain of optimization. These tools written in Rust are somehow 100× as fast despite not being optimized at all.
JavaScript is so slow that you have to optimize stuff, with Rust (and other performant languages) you don't even need to because performance just doesn't bubble up as a problem at all, letting you focus on building the actual tool.
