React Hooks are functions that let you use state and other React features in functional components. The most common hooks are useState, useEffect, and useContext. Hooks make code cleaner, easier to read, and easier to reuse. They were introduced in React 16.8 and have become the standard way to write React components today. Use State lets you add state to functional components; useEffect lets you perform side effects like fetching data or updating the DOM. useContext lets you share data between components without passing props.
