Introduction to React Hooks for Beginners
React Hooks revolutionized how we write React components. Let's explore the basics.
What are Hooks?
Hooks are functions that let you "hook into" React state and lifecycle features from function components.
Essential Hooks
useState
const [count, setCount] = useState(0);
Allows you to add state to functional components.
useEffect
useEffect(() => {
document.title = `Count: ${count}`;
}, [count]);
Handles side effects like data fetching and DOM manipulation.
useContext
Access context values without prop drilling.
Rules of Hooks
- Only call Hooks at the top level
- Only call Hooks from React functions
Mastering these basics will set you up for success with React development!
