What are React Hooks?

React Hooks are functions that let you use state and other React features in functional components. They were introduced in React 16.8.\n\nCommon hooks:\n- useState: Manages component state\n- useEffect: Handles side effects\n- useContext: Consumes context\n- useReducer: Complex state management\n\nExample:\nfunction Counter() {\n const [count, setCount] = useState(0);\n \n useEffect(() => {\n document.title = `Count: ${count}`;\n }, [count]);\n \n return (\n setCount(count + 1)}>\n {count}\n \n );\n}
