I don’t thinks hooks are a great example. Hooks are by definition effectful. Best compared to ‘Applicative’s in Haskell. (Not monadic unfortunately)

So a functional component in react using hooks is not pure. You can translate it into FP with a bit of magic, but requires a context. The line is not that distinct at all.

Hooks themselves may not be good FP examples, however I meant the resultant functional components that you develop yourself usually are.

Hooks are implicitly injecting whatever global state in your stateless components, so definitely not a good example of functional concepts imho.
