I am getting into the frontend dev and one thing that I don't understand is why people use bun in the first place? It's not much better preforming, it's not much safer, it's still not 100% compliant. Some tests show it's actually slower than node. Why bother switching, then?

Faster package manager

Faster startup

Typescript support out of the box

Better stdlib than node

Stdlib includes yaml, sqlite etc so you need to pull in fewer deps, so you can avoid the left-pad/is-even node_modules explosion problem to a greater extent

I don’t think you would use Bun for front end.

So much of JS dev is just saying no to random new stuff, Bun included

i assume it's because of all the built in tooling that node doesn't ship with.
