I’m looking forward to useActionState in React 19.

Here are six useActionState benefits:

1. No event.preventDefault needed.

2. Can read the form’s pending state via useFormStatus. No extra useState calls required.

3. Progressive enhancement - can submit form even if React hasn’t fully loaded on the client.

4. The action is automatically treated as a transition, which optimizes rendering performance.

5. Anything that happens during the action which triggers components to suspend is part of the same transition.

6. React manages errors and race conditions to ensure the form’s state is always correct.
