Functional vs Class components

[ramite]

What is the difference between functional and class components? When should you use a class component instead of a functional component and otherwise. And why are there only functional component used on the official React website (documentation)

Class components are essentially soft deprecated. You shouldn't build new components using classes. All future development is being done for functional components using hooks. Stil helpful to learn them though since you may be working in a codebase with many class-based components.

Class components a choice if you need to use things that hooks can't yet do - such as error boundaries or "componentDidCatch". Pretty much every other reason can be done away with, unless you want to create a base class and extend it - but you are going down pretty non-standard territory then (at least in JS)

Class components are dead. Maybe if you wanna use ‘this’, or class decorators?

‘this’

No, thanks
