I have seen React.js 16.8.x release notes. They introduced Hooks in react.

Could someone explain this with one example that would explain functionalities and working of hooks?

So the questions are:

• What is the hooks and when to use?
• Is it useful to replace class component with function component?
• Should it is used as alternative of redux?
• What do they mean by Hooks allow you to reuse stateful logic without changing your component hierarchy. ?

For first question:

Hooks allow you to access state and Lifecycle methods in a functional component, so you don't need to write class component.

Hooks are not alternative to redux,

• Hooks state is limited to component whereas Redux Store can be accessed in entire app
• Hooks does not maintain single store like redux does.
