You can rip fast builds from my cold, dead hands. I’m not looking back to JS-only tooling, and I was there since the gulp days.

All I can say for sure is that the reason the old tools were slow was not that the JS runtime is impossible to build fast tools with.

And anyway, these new tools tend to have a "perf cliff" where you get all the speed of the new tool as long as you stay away from the JS integration API sued to support the "long tail" of uses cases. Once you fall off the cliff though, you're back to the old slow-JS cost regime...

I don't have them at hand right now but there are various detailed write-ups from the maintainers of Vite, oxc, and more, that are addressing this specific argument to point out that indeed the JavaScript runtime was a hard limitation on the throughput they could achieve, making Rust a necessity to improve build speeds.
