Are React classes deprecated?
Will React Classes stay with us much longer? Before you say anything, yes, I am aware that React’s official documentation states that there are no plans to deprecate class components any time soon, so don’t worry, you don’t have to go out and re-write your entire code.

Do people still use class-based components?

Tthe Facebook team recommends that all new React code is hook-based functional components, and not class-based. You can mix class components and hook-based components, so there is no reason to rewrite your class components.
Are functional components better?
Performance optimization: There isn’t really a difference in terms of which components benefit you more performance-wise; however, since functional components don’t have access to methods like shouldComponentUpdate and PureComponent , it could be a bit of an inconvenience to optimize them for performance.
What is the difference between React React and React Redux?
React also lets us write custom hooks, which let us extract reusable hooks to add our own behavior on top of React’s built-in hooks. React Redux includes its own custom hook APIs, which allow your React components to subscribe to the Redux store and dispatch actions.
Is the React-Redux hooks API production-ready?
The React-Redux hooks API has been production-ready since we released it in v7.1.0, and we recommend using the hooks API as the default approach in your components. However, there are a couple of edge cases that can occur, and we’re documenting those so that you can be aware of them .
Is it possible to avoid using Redux?
In React for example there are many ways to avoid using Redux: children props, the context API. But for medium to bigger projects I always found Redux (or an equivalent) almost mandatory: state management libraries beautifully keep logic and behaviours abstracted away from the UI.
What are the best resources to learn react?
There are countless React tutorials online if you want to refresh your understandings, but if you’re just starting out I suggest reading Getting Started with React by Tania Rascia.
