对对象中的字符串日期进行排序

// 假设对象数组为dates，包含日期字符串属性为dateString
var dates = [
  { dateString: "2022-01-01" },
  { dateString: "2022-03-15" },
  { dateString: "2021-12-25" }
];

// 将日期字符串转换为日期对象
dates.forEach(function(obj) {
  obj.date = new Date(obj.dateString);
});

// 使用快速排序算法对日期对象进行排序
function quickSort(arr) {
  if (arr.length <= 1) {
    return arr;
  }
  
  var pivotIndex = Math.floor(arr.length / 2);
  var pivot = arr.splice(pivotIndex, 1)[0];
  var left = [];
  var right = [];
  
  for (var i = 0; i < arr.length; i++) {
    if (arr[i] < pivot) {
      left.push(arr[i]);
    } else {
      right.push(arr[i]);
    }
  }
  
  return quickSort(left).concat([pivot], quickSort(right));
}

dates = quickSort(dates);

// 将日期对象转换回字符串形式
dates.forEach(function(obj) {
  obj.dateString = obj.date.toLocaleString();
  delete obj.date;
});

console.log(dates);
