This makes your method markedly less useful than `localeCompare`. It's
really useful to know not just that the strings are equal or not equal, but
how they relate to one another lexicographically. For instance, for sorting:

```js
const array = ["c", "a", "B"];
array.sort((a, b) => a.localeCompare(b, undefined, {sensitivity: "base"}));
console.log(array); // "a", "B", "c"
```
