What is hooks and type of hooks used in the react.Js

React Hooks are simple JavaScript functions that we can use to isolate the reusable part from a functional component. Hooks can be stateful and can manage side-effects.

React provides a bunch of standard in-built hooks:

• useState: To manage states. Returns a stateful value and an updater function to update it.
• useEffect: To manage side-effects like API calls, subscriptions, timers, mutations, and more.
• useContext: To return the current value for a context.
• useReducer: A useState alternative to help with complex state management.
• useCallback: It returns a memorized version of a callback to help a child component not re-render unnecessarily.
• useMemo: It returns a memoized value that helps in performance optimizations.
• useRef: It returns a ref object with a .current property. The ref object is mutable. It is mainly used to access a child component imperatively.
• useLayoutEffect: It fires at the end of all DOM mutations. It’s best to use useEffect as much as possible over this one as the useLayoutEffect fires synchronously.
• useDebugValue: Helps to display a label in React DevTools for custom hooks.
