如何摆脱函数中的代码重复？（如果块是明显的重复）

function sortStrings(arr, param = 'asc') {
  const arrCopy = [...arr];

  if (param === 'asc') {
    arrCopy.sort((a, b) => a.localeCompare(b, ['ru', 'eng'], { caseFirst: 'upper' }));
  }

  if (param === 'desc') {
    arrCopy.sort((a, b) => -a.localeCompare(b, ['ru', 'eng'], { caseFirst: 'lower' }));
  }

  return arrCopy;
}
