As someone who have been using Deno for the last few years, is there anything that Bun does better? Bun seems to use a different runtime (JSC) which is less tested than V8, which makes me assume it might perform worse in real-world tasks (maybe not anymore?). The last time I checked Bun's source code, it was... quite messy and spaghetti-like, plus Zig doesn't really offer many safety features, so it's not that hard to write incorrect code. Zig does force some safety with ReleaseSafe IIRC, but it's still not the same as even modern C++, let alone Rust.

I'll admit I'm somewhat biased against Bun, but I'm honestly interested in knowing why people prefer Bun over Deno.

I haven't used Deno, but I do use Bun purely as a replacement for npm. It does the hard-linking thing that seems to be increasingly common for package managers these days (i.e. it populates your local node_modules with a bunch of hard links to its systemwide cache), which makes it vastly quicker and more disk-efficient than npm for most usage.

Even with a cold cache, `bun install` with a large-ish dependency graph is significantly faster than `npm install` in my experience.

I don't know if Deno does that, but some googling for "deno install performance vs npm install" doesn't turn up much, so I suspect not?

As a runtime, though, I have no opinion. I did test it against Node, but for my use case (build tooling for web projects) it didn't make a noticeable difference, so I decided to stick with Node.

IIRC bun zig code base has a lot of fine optimization too. I think the lead did a conference explaining his work. Or maybe i'm confused.
