React Hooks are functions that allow you to use state and lifecycle methods in functional components. They were introduced in React 16.8 and have become a popular way to manage state and side effects in React applications.
There are several built-in hooks in React, including useState, useEffect, useContext, useReducer, useCallback, useMemo, useRef, and useImperativeHandle. These hooks allow you to manage component state, fetch data from APIs, handle events, and more.
Using hooks can simplify your code and make it easier to reuse logic between components. They also encourage a more functional programming style, which can make your code more declarative and easier to reason about.
However, it's important to note that not all components need to use hooks. Class components and lifecycle methods are still a valid way to manage state and side effects in React, and you should choose the approach that best fits your use case.
