And to add onto that, `strings.sort((a, b) => a.localeCompare(b))` is equivalent to `strings.sort(new Intl.Collator().compare)`, just slightly less efficient.

Case-insensitive comparisons can't really be done in a language-independent manner, and my `String.compare` is just lexicographic and based on character code order. It's not actually useful for language in general, and as `.sort` does that by default, it's not useful there. However, it's useful for things like binary search of a sorted list of strings or other similar low-level locale-independent string tasks.
