How does this function validate its input — does it throw on bad arguments?

Yes, the function validates its input and throws on bad arguments.

The validation occurs at the very start of the function [index.js:L2-L4]:

```javascript
if (typeof string !== 'string') {
	throw new TypeError('Expected a string');
}
```

If you pass anything other than a string, it will throw a `TypeError` with the message `'Expected a string'`. This ensures the function only operates on actual strings before proceeding to the escaping logic.
