Discussion on: Setting state for parent from within useEffect hook in child component causes an infinite loop

Seems quite normal and expected to me. Changing the state in the child will trigger another render for the child because state is sent as a prop to it and it will repeat again.

useEffect in the way you used it is equivalent to componentDidMount

Either if you don't pass state as a prop you still get an infinite loop. I think when parent component re-renders, child component unmount and mounts, so is, as you say, componentDidMount, so that's why useEffect code always executes.
