Introduction to React Hooks
React Hooks are a powerful feature introduced in React 16.8 that allow you to use state and other React features without writing a class. Hooks enable functional components to manage state and side effects, making your code more concise and easier to understand.
Hooks are functions that let you “hook into” React state and lifecycle features from function components. The most commonly used hooks are useState and useEffect.
"Hooks allow you to use state and other React features without writing a class, simplifying your component logic."
The useState hook lets you add state to your functional components:
import React, { useState } from 'react'; function Counter() { const [count, setCount] = useState(0); return setCount(count + 1)}>Count: {count}; }
The useEffect hook allows you to perform side effects in your components:
useEffect(() => { document.title = `Count: ${count}`; }, [count]);
Hooks are a game-changer for React development, allowing for cleaner and more maintainable code.
