indexToDelete becomes -1 (it is a JavaScript spec [mathematical number](https://tc39.es/ecma262/#sec-mathematical-operations), and so the loop does not run. I don't think there's any need to special case this.

I'll close since I think it's pretty clear given how numbers work... let me know if you disagree.
