无法根据 S3 存储桶的创建日期创建排序数组

Question

我正在尝试根据创建日期（最新的在前）对 s3 存储桶数组进行排序。我在排序数组中多次重复相同的数组。我知道我在这里错过了一些东西，但无法弄清楚是什么。我的代码是：

var bucketListArr = [];
for (var index in data.Buckets) {
    var bucket = data.Buckets[index];
    //if(bucketList[index] == null) bucketList[index] = [];
    bucketListArr.push({
         "bucketName": bucket.Name,
         "creationDate": bucket.CreationDate
    });
    // bucketList[index][0] = bucket.Name;
   // bucketList[index][1] = bucket.CreationDate;
 }
 var sortedBucketListArr = [];
 //console.log("Bucket List :: ", bucketList, " length :: " , bucketList.length );
 for(var i= 0;i < bucketListArr.length; i++){
    for(var j = i + 1; j< bucketListArr.length; j++){
       if(bucketListArr[i].creationDate >= bucketListArr[j].creationDate){
          sortedBucketListArr.push({
                   "bucketName": bucketListArr[i].bucketName,
                   "creationDate": bucketListArr[i].creationDate
          });
     }
   }
 }
 console.log("Sorted List :: ", sortedBucketListArr);

提前感谢任何帮助。

我能够解决这个问题。问题是日期存储为字符串。因此，它需要转换为 Date，然后才能在 date 属性上对数组进行排序。我将代码更改为：

var bucketListArr = [];
for (var index in data.Buckets) {
    var bucket = data.Buckets[index];
    //if(bucketList[index] == null) bucketList[index] = [];
    bucketListArr.push({
         "bucketName": bucket.Name,
         "creationDate": bucket.CreationDate
    });
}
bucketListArr.sort(function (a, b) {
        var dateA = a.creationDate, dateB = b.creationDate;
        return dateB - dateA;//a.strParamToSortOn < b.strParamToSortOn;
});
console.log("Sorted List :: ", bucketListArr);
