Woah, `ref` as a function is secretly so powerful. No more `undefined` checks and useEffects just to add some document event listeners. Handle everything with a function in-line 👍

unless refs changed while i wasn’t looking you need to wrap this in `useCallback`, otherwise it’ll call both the cleanup and setup function again every single render

Looking forward to the compiler leaving beta to make React feel less esoteric in situations like this

The compiler won't wrap an inline function here in useCallback for you because it changes semantics. /cc @gsathya.bsky.social

Hmm isn't it the same as having a useEffect without dependency array, and then adding an empty one to it? That changes st which time / how often it runs.

I'm referring to this discussion: bsky.app/profile/gsat...

What’s the use case for needing to run every render? Seems like a hacky way to do side effects in render
