One nice thing about bun was/is that you can feed it TypeScript files directly, to run them locally. No need to transpile first. Much like deno.

I tried it out for a few hobby side projects as someone that doesn’t do much JavaScript development.

It delivered on the dev experience. I didn’t have to learn how to plug a bunch of random tools together because bun had a lot of the basic stuff just bundled in.

Task runner, test runner, typescript, etc.

I think if I spent more time doing JavaScript development work it wouldn’t have really mattered, that project bootstrapping is a one time cost and if you know how to do it it’s cheap enough. As someone that spends most of their time writing other languages though it was nicer than figuring out how to get a bunch of tools to play nice with each other.

I heard of people using it on hobby projects.

Don’t know of any firm using it in production. Node.js never really had scale issues that needed addressing.

I’ve moved more towards deno recently. No real desire for bun on my end
