All true. I work on a massive React codebase and it is a challenge to follow the logic because at any given time there could be a dozen effects firing off from a single state change. Granted, having the dependency array helps follow what's firing off, but when effects kick off other effects it gets into a mess. (Probably a sign that we should refactor some things) This problem isn't solved by class-based components either; years ago when I first started working on the codebase I found class-based components with gigantic componentDidUpdate() full of hard to follow conditionals and setting state. That said, hooks makes it easier to refactor problems like this in my experience.
