The phrasing was poor, but I had in mind a whole engine or stack, and not just a language in isolation.

Basically benchmarks like these:

https://programming-language-benchmarks.vercel.app/typescrip...

To note, the first link has a follow-up with Go properly getting faster than deno when fitted with a better http server. Which is kinda my point: the tooling available and level of optimizations can easily have more impact than the language's inherent speed.

no sure it is relevant, probably all heavy lifting done in C++ and Rust https://searchfox.org/mozilla-central/search?q=render&path=&...
