React Component Patterns

Build maintainable React components using modern patterns.

Functional Components with Hooks

Always prefer functional components over class components:

import { useState, useEffect, useCallback } from 'react';

interface UserProps {
  userId: string;
  onUpdate?: (user: User) => void;
}

export function UserProfile({ userId, onUpdate }: UserProps) {
  const [user, setUser] = useState<User | null>(null);
  const [loading, setLoading] = useState(true);
