Not accurate. Bun is a batteries-included JavaScript & CSS transpiler (parser), minifier, bundler, npm-like package manager, Jest-like test runner, as well as runtime APIs like a builtin Postgres, MySQL and Redis client. This is naturally a ton of code.

Now that Bun can leverage Rust do you think some of this code will get disaggregated? Eg, Bun could use swc crates

    It wouldn't have been that hard to do that from Zig if they'd wanted to. They don't, because they want to do everything themselves so that it works exactly the way they want (except the core JS engine for which this is infeasible—though even that has custom patches). After all, there are already plenty of libraries on npm for those other parts of the stack and they do work in Bun.
