We had many languages that are faster that are not c/c++.
Compare Go (esbuild) to webpack (JS), its over 100x faster easily.
For a dev time matters, but is relative, waiting 50sec for a webpack build compared to 50ms with a Go toolchain is life changing.
But for a dev waiting 50ms or 20ms does not matter. At all.
So the conclusion is javascript devs like hype, and flooded Rust and built tooling for JS in Rust. They could have used any other compiled languge and get near the same peformance computer-time-wise, or the exact same time human-timewise.

It absolutely does:

To win benchmark games it does, in a world where people keep shipping Electron crap, not really.
Not sure if you missed the /s?
Anyway, you posted about speed, and then followed by a link to some python related thing. In python speed has never been a key tenet, at least when it comes to pure cpu based calculations. How much tooling is built in python? All the modern python tooling is mostly Rust based too. So theres that.
I mean for a dev working in JS with JS built tooling the speed is not in milliseconds, but in seconds, even minutes.
I still think my point holds, having a build take int he 10s of seconds vs 50ms is very much good enough for development (the usual frontend save and refresh browser cycle)
No worries, when Zig hits 1.0, the RIZ projects from JavaScript, Python and Ruby tooling will start hitting HN frontpage.
