Hooks are the new feature introduced in the React 16.8 version. It allows us to use state and other React features without writing a class. Hooks are the functions which "hook into" React state and lifecycle features from functional components.

> ### Rules of Hooks:-
 >1.Only call Hooks at the top level.                                                                                               
 >2.Only call Hooks inside React functions.

 >1.useState: To manage states. Returns a stateful value and an updater function to update it.          
 >2.useEffect: To manage side-effects like API calls, subscriptions, timers, mutations, and more.         
 >3.useContext: To return the current value for a context.                                                                
 >4.useReducer: A useState alternative to help with complex state management.                
 >5.useCallback: It returns a memorized version of a callback to help a child component not re-               render unnecessarily.                                                                                              
 >6.useMemo: It returns a memoized value that helps in performance optimizations.         
 >7.useRef: It returns a ref object with a .current property. The ref object is mutable.
