+The `@astrojs/react` integration provides two functions for use with [Astro Actions][astro-actions]: `withState()` and `getActionState()`.
 
 These are used with [React's useActionState() hook](https://react.dev/reference/react/useActionState) to read and update client-side state when triggering actions during form submission.

-The `experimental_withState()` function will match the action's types with React's expectations and preserve metadata used for progressive enhancement, allowing it to work even when JavaScript is disabled on the user's device.

-You can access the state stored by `useActionState()` on the server in your action `handler` with `experimental_getActionState()`. It accepts the [Astro API context](/en/reference/api-reference/#the-context-object), and optionally, you can apply a type to the result.
