+- Use `React.useState()` to create a `data` state variable and set its initial value equal to the `options` prop.
 - Create a function `toggle` that is used to toggle the `checked` to update the `data` state variable and call the `onChange` callback passed via the component's props.
 - Render a `<ul>` element and use `Array.prototype.map()` to map the `data` state variable to individual `<li>` elements with `<input>` elements as their children.
 - Each `<input>` element has the `type='checkbox'` attribute and is marked as `readOnly`, as its click events are handled by the parent `<li>` element's `onClick` handler.
