Answer 1

Use The Intl.Collator like you will get perfect sorting result

function letterSort(lang, letters) {
  letters.sort(new Intl.Collator(lang).compare);
  return letters;
}

console.log(letterSort('gu', ['છ','ક','ખ']));
// expected output: Array ["a", "ä", "z"]

console.log(letterSort('sv', ['a','z','ä']));
// expected output: Array ["a", "z", "ä"]
