I agree with the others. I've started using hooks since they were introduced and I've only hit the re-render issue only a few times, which I promptly fixed as they were caused by carelessness. My strategy is to not use a single useEffect, but multiple ones for each (which reduce greatly the dependencies). Also, avoiding dependency circles between useState and useEffect.

I've used class components and I think hooks are much better than the monstrosity that the lifecycle methods would usually become.

Also defining functions inside other functions is very much the staple of functional programming.
