codeUnitComparatorAsc

コードユニット値に基づいて文字列を昇順にソートする比較関数です。これは Vanilla JavaScript の Array.prototype.sort で使用されるデフォルトの順序です。

export const codeUnitComparatorAsc = (a: string, b: string) => {
  if (a < b) return -1
  if (b > a) return 1
  return 0
}

codeUnitComparatorDesc

コードユニット値に基づいて文字列を降順にソートする比較関数です。

Added in v0.0.2

Source

export const codeUnitComparatorDesc = (a: string, b: string) => {
  if (a < b) return 1
  if (b > a) return -1
  return 0
