Answer 1

I would use class when there is something that functional components can't implement like state or lifecycle methods, waitttttttttttttttttt...

(当功能组件无法实现的某些东西（例如状态或生命周期方法），waitttttttttttttttttttttt时，我将使用类...)

Since hooks have the state and lifecycle methods you don't need classes anymore :)

(由于钩子具有状态和生命周期方法，因此您不再需要类 :))
