Hooks

Hooks are functions introduced in React 16.8 that allow developers to use state, side effects, and other React features inside functional components—eliminating the need for class components in most scenarios. Hooks fundamentally changed how React apps are written, making functional components more powerful, concise, and reusable.

They help encapsulate logic in a clean, modular way and encourage composability by enabling developers to build custom hooks for shared behaviors.

Core Built-in Hooks:

useState: Adds local state to a function component.

const [count, setCount] = useState(0);
useEffect: Handles side effects like data fetching or subscriptions. useEffect(() => {
  document.title = `Count: ${count}`;
}, [count]);
useContext: Accesses context values without using a Consumer. const theme = useContext(ThemeContext);

• useRef, useReducer, useMemo, and others provide advanced capabilities.

Custom Hooks

Hooks are composable, which means you can build your own:

function useLocalStorage(key, initialValue) {
  const [value, setValue] = useState(() =>
    JSON.parse(localStorage.getItem(key)) || initialValue
  );
  useEffect(() => {
    localStorage.setItem(key, JSON.stringify(value));
  }, [value]);
  return [value, setValue];
}

Why Hooks Matter

Hooks provide:

• Cleaner component structure by avoiding lifecycle methods and this.

• Reusability of logic via custom hooks.

• Better separation of concerns within components.

• A functional programming approach aligned with modern JavaScript patterns.
