redux解决了状态管理问题，在一个地方集中管理，但是设置的过程复杂，使用也很复杂，那么为什么要用了？
为什么不用React Context API 和 React Hooks了？
Context provides a way to pass data through the component tree without having to pass props down manually at every level.
The React Context API is React’s way of managing state in multiple components that are not directly connected.
React Hooks provide an alternative to writing class-based components by allowing us to easily handle state management from functional components.
