Question

Accepted Answer

**React 19** introduces several new hooks:

**1. use()**
```tsx
// Read resources in render
const data = use(promise);
const theme = useContext(ThemeContext);
```

**2. useFormStatus**
```tsx
// Form submission status
const { pending } = useFormStatus();
```

**3. useOptimistic**
```tsx
// Optimistic updates
const [optimistic, addOptimistic] = useOptimistic(state, updateFn);

// Form actions with state
const [state, action, pending] = useActionState(fn, initial);
```
