1- State Hooks

useReducer manage state in a more predictable and maintainable way, especially when dealing with complex state logic.
2-Context Hook
The useContext hook is a valuable tool in the React developer’s toolkit, making it easier to manage and share state across components without the trouble of prop drilling.
3-ref Hook
The useRef hook is a powerful tool in the React ecosystem, offering a flexible and efficient way to reference DOM elements
4-Effect Hook
useEffect is a hook that allows us to perform side effects in functional components. Side effects are operations that interact with external systems, such as data fetching, subscriptions, timers, and manually changing the DOM.
5-Performance
useMemo is a React hook that allows us to memoize expensive calculations. Memoization is an optimization technique where the result of a function call is cached and returned when the same inputs occur again, instead of recalculating the result.
useCallback is an essential hook for optimizing performance in React applications by memoizing callback functions. It’s particularly useful when passing callbacks to child components that rely on reference equality
