React 19: useActionState

Video Description

In this video, we'll build a form using React's new useActionState hook, introduced in React 19. Along the way, we'll explore other exciting features from React 19, including form actions, server functions, and server components. Learn how these tools make building forms easier than ever! One thing I forgot to mention: useActionState can only be used inside client components. That's why we have a separate registration form component — it's a client component, but I forgot to show/explain that in the video.
