### TextArea
Renders a `<textarea>` 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 `<textarea>` element.
Render a `<textarea>` element with the appropriate attributes and use the `callback` function in the `onChange` event to pass the value of the textarea to the parent.
```jsx
function TextArea({
callback,
cols = 20,
rows = 2,
disabled = false,
readOnly = false,
placeholder = ''
}) {
return (
<textarea
cols={cols}
rows={rows}
disabled={disabled}
readOnly={readOnly}
placeholder={placeholder}
onChange={({ target: { value } }) => callback(value)}
/>
);
}
```
```jsx
ReactDOM.render(
<TextArea placeholder="Insert some text here..." callback={val => console.log(val)} />,
document.getElementById('root')
);
```
