 Renders a password input field with a reveal button.
 
-Initially set `state.shown` to `false` to ensure that the password is not shown by default.
-Create a method, `toggleShown`, which uses `Component.prototype.setState` to change the input's state from shown to hidden and vice versa, bind it to the component's context.
-In the`render()` method, use a`<div>` to wrap both the`<input>` and the `<button>` element that toggles the type of the input field.
-Finally, bind the `<button>`'s `onClick` event to the `toggleShown` method.
+Use the `React.useState()` hook to create the `shown` state vairable and set its value to `false`.
+Use a`<div>` to wrap both the`<input>` and the `<button>` element that toggles the type of the input field between `"text"` and `"password"`.
