Renders an `<input>` element that uses a callback function to pass its value to the parent component.
- Use object destructuring to set defaults for certain attributes of the `<input>` element.
- Render an `<input>` element with the appropriate attributes and use the `callback` function in the `onChange` event to pass the value of the input to the parent.
```jsx
const UncontrolledInput = ({
callback,
type = 'text',
disabled = false,
readOnly = false,
placeholder = ''
}) => {
return (
<input
type={type}
disabled={disabled}
readOnly={readOnly}
placeholder={placeholder}
onChange={({ target: { value } }) => callback(value)}
/>
);
};
```
```jsx
ReactDOM.render(
<UncontrolledInput
type="text"
placeholder="Insert some text here..."
callback={val => console.log(val)}
/>,
document.getElementById('root')
);
```
