[Request for comment] Is there any potential issues handling componentDidMount and componentDidUp with useHooks in this manner?

useEffect.js

const once = useRef(false)
useEffect(() => {

	if(once.current === false){
		once.current = true
		// do things as were in componentDidMount
		return
	}

	// do things as were in componentDidUpdate

	// clean up
	return () => {
		//
	}
}) // <- no need to pass in 2nd argument
