this is so far from the truth. Bun, Zig, and uWebsockets are passion projects run by individuals with deep systems programming expertise. furthest thing from vibe coding imaginable.
> a decade of performance competition in the JS VM space
this was a rising tide that lifted all boats, including Node, but Node is built with much more of the system implemented in JS, so it is architecturally incapable of the kind of performance Bun/uWebsockets achieves.
That sounds like an implementation difference, not an architectural difference. If they wanted to, what would prevent Node or a third party from implementing parts of the stdlib in a faster language?
Sure, I definitely will not throw projects like Zig into that bucket, and I don't actually think Bun is vibe-coded. At least that _used_ to be true, we'll see I guess...
Don't read a snarky comment so literally ;)
The key architectural difference is that Node.js implements the HTTP stack and other low level libraries in JavaScript, which gives it memory safety guarantees provided by the v8 runtime, while Bun/uWebsockets are a zig/C++ implementation. for Node.js, which is focused on enterprise adoption, the lower performance JS approach better aligns with the security profile of their enterprise adoption target.
