Frontend Development

Modern web development relies heavily on component-based architectures.

The DOM

The Document Object Model (DOM) is a programming interface for web documents. It represents the page so that programs can change the document structure, style, and content.

State Management

Managing state is crucial for interactive applications.

const [user, setUser] = useState(null);

useEffect(() => {
  fetchUser().then(data => setUser(data));
}, []);
