The `useFormStatus` hook from React is a useful tool for managing the state of form inputs and other components that need to display a status, like validation errors or submission success.

Here's a breakdown of how it works:

**What does useFormStatus do?**

`useFormStatus` returns an object with three properties: `success`, `error`, and `submitting`. These values represent the current state of the form input or component being managed by this hook.

- `success`: Indicates whether the form submission was successful (i.e., `true`) or not (`false`).
- `error`: Represents any error messages associated with the form's submission. This can be a string if there's an issue, and it might also be `null` if everything is fine.
- `submitting`: A boolean that indicates whether the component is currently submitting its data (i.e., true) or not (`false`). When this is set to `true`, you might want to show a loading indicator to let users know something is happening.

**How do I use useFormStatus?**

You can use `useFormStatus` by wrapping your component with it, like so:

```jsx
import { useFormStatus } from 'react-hook-form-status';

function MyForm() {
const { success, error, submitting } = useFormStatus();

if (submitting) return <div>Loading...</div>;

if (success)
return (
<div>
Data submitted successfully!
{/* Add a button to resubmit or add more functionality here */}
</div>
);

if (error)
return (
<div style={{ color: 'red' }}>
Something went wrong. {error}
{/* Add a button to retry or display the error message clearly */}
</div>
);

return (
<form onSubmit={/* Your submit handler here */}>
{/* Form fields go here */}
</form>
);
}
```

**Key aspects:**

- Use `useFormStatus` where you have form inputs and need to indicate their status (like validation errors or a successful submission).
- The returned object (`success`, `error`, `submitting`) is what you'll use to conditionally render different messages or components based on the current state of your form.
- Remember, this hook integrates nicely with React Hook Form for managing form data and validation.

In summary, `useFormStatus` simplifies handling various states of a form within your component, making it easy to display status messages (success, error) while the form is being processed or after submission.
