How does React manage state?

Which state management is best in React? React’s useState is the best option for local state management . If you need a global state solution, the most popular ones are Redux, MobX, and built-in Context API.

Hooks are a new addition in React 16.8. They let you use state and other React features without writing a class . Building your own Hooks lets you extract component logic into reusable functions.
