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.

Search for pointer exceptions or core dumps on Bun's GitHub issues and you'll see why people (should) use Deno over Bun, if only because Rust is a way more safe language than Zig.

I haven't verified this, but I would be willing to bet that most of Bun's issues here have more to do with interfacing with JavaScriptCore through the C FFI than Zig itself. this is as much a problem in Rust as it is in Zig. in fact, it has been argued that writing unsafe Zig is safer than writing unsafe Rust: https://zackoverflow.dev/writing/unsafe-rust-vs-zig/

As someone who has researched the internals of Deno and Bun, your unverified vibe thoughts are flat out wrong. Bun is newer and buggier and that's just the way things go sometimes. You'll get over it.
