Mastering React Hooks in 2024

Introduction to React Hooks

React Hooks have revolutionized how we write components. They allow us to use state and other React features without writing a class. #

useState

The `useState` hook is the most fundamental hook. It allows you to add state to functional components.

const [count, setCount] = useState(0);

#

useEffect

The `useEffect` hook lets you perform side effects in functional components. Data fetching, subscriptions, and manually changing the DOM are all examples of side effects.

useEffect(() => {
  document.title = `You clicked ${count} times`;
}, [count]); // Only re-run the effect if count changes

Advanced Hooks

- `useReducer`: An alternative to `useState` for complex state logic. - `useCallback` & `useMemo`: For performance optimizations. - `useRef`: For accessing DOM elements or storing mutable values that don't trigger re-renders. This post will explore creating powerful custom hooks to encapsulate logic and share it across your application.
