Renders a password input field with a reveal button.
- Use the `useState()` hook to create the `shown` state variable and set its value to `false`.
- When the `<button>` is clicked, execute `setShown`, toggling the `type` of the `<input>` between `'text'` and `'password'`.
```jsx
const PasswordRevealer = ({ value }) => {
const [shown, setShown] = React.useState(false);
return (
<>
<input type={shown ? 'text' : 'password'} value={value} />
<button onClick={() => setShown(!shown)}>Show/Hide</button>
</>
);
};
```
```jsx
ReactDOM.render(<PasswordRevealer />, document.getElementById('root'));
```
