I see increasingly hooks described as an alternative to classes. But hooks are really just something you can use in functional components. Functional components are the alternative to classes and don't require hooks
Correct, yes. Hooks are what enables function components to replace classes though- otherwise you can have local state. You could do everything in redux though say, and you wouldn’t need ‘useState’
Hooks help functions replace classes only when those class components used state or life cycle. Otherwise it could have used a functional component all along and that's always been the alternative to classes. I'm not sure what my point was anymore but it's fun to discuss
:) Yes - you're correct; the main use case for hooks is state or lifecycle (useEffect). You can also use useRef for reference though, useContext for context, and a few other things - but useState is probably most of the usage.
