Understanding Prop Drilling vs Context

Prop drilling occurs when you pass props through multiple layers of components that don't need them, just to reach a deeply nested component.

// Prop Drilling (AVOID)
function App() {
  const [user, setUser] = useState<User | null>(null);
  return <Layout user={user} setUser={setUser} />;
}

function Layout({ user, setUser }: Props) {
  // Layout doesn't use user, just passes it down
