Same with bun, it looks like node is leaving some performance on the table (maybe for backward compatibility or maybe because nobody bothered to improve it)

Bun doesn't use V8, so there are other performance differences there

It is fair to note, that JavascriptCore outperforms V8 already. However, it is in Zig. And Deno is in Rust.
