如何在Javascript中按天和月对日期数组排序

function compareDates(date1, date2) {
  return date1.getTime() - date2.getTime();
}

dateArray.sort(compareDates);

function compareMonths(date1, date2) {
  return date1.getMonth() - date2.getMonth();
}

dateArray.sort(compareMonths);

var dateArray = [
  new Date('2022-01-01'),
  new Date('2022-01-05'),
  new Date('2022-02-01'),
  new Date('2022-02-05'),
  new Date('2022-03-01'),
  new Date('2022-03-05')
];

function compareDates(date1, date2) {
  return date1.getTime() - date2.getTime();
}

function compareMonths(date1, date2) {
  return date1.getMonth() - date2.getMonth();
}

dateArray.sort(compareDates);
console.log('按天排序:', dateArray);

dateArray.sort(compareMonths);
console.log('按月排序:', dateArray);
