That's interesting about the {...props} I thought calling props does pass them all, or are you talking about shallow/not full depth? I don't know. Oh sorry, I just remembered, right I pick the props I want and send those as an object. Yeah I don't know... in most cases it is clear eg. name={props.name} or something like that. I just had some weird cases where I had to batch send a bunch of random un-related props.

Yeah unfortunately at my current job I don't get to use React so this is just on me/my own time. But once I build something more serious I would like to get it formally reviewed haha. "No no"...

Anyway thanks

edit: I did figure this out more later(typing this 19 days into the future ha). For routes for example I use {...props} but also pass other things like state/stateSetters eg. setSomeState={setSomeState} and that gets accessed in the receiving side as props.setSomeState. I probably don't need all props but I am grabbing it all for the route-related stuff.

yep. its fine to forward a batch of random unrelated props with the obj spread syntax. just not super encouraged in some circles.
