前提

做前后端分离,现有如下数组按照updated_at倒序，根据year做第一级，month做第二级,拼装成多维数组，原先是在php后端进行排序处理，但是通过json传递到前端变成无序，现在想通过js，该如何处理？

[
    {
        "id": 15,
        "year": "2018",
        "month": "03",
        "updated_at": "2018-03-01 15:09:59"
    },
    {
        "id": 14,
        "year": "2018",
        "month": "02",
        "updated_at": "2018-02-24 21:39:53"
    },
    {
        "id": 13,
        "year": "2017",
        "month": "12",
        "updated_at": "2017-12-02 16:45:03"
    },
    {
        "id": 5,
        "year": "2017",
        "month": "11",
        "updated_at": "2017-11-10 17:32:11"
    },
    {
        "id": 7,
        "year": "2017",
        "month": "11",
        "updated_at": "2017-11-07 17:26:09"
    },
    {
        "id": 9,
        "year": "2017",
        "month": "10",
        "updated_at": "2017-10-23 19:08:12"
    },
    {
        "id": 8,
        "year": "2017",
        "month": "10",
        "updated_at": "2017-10-20 20:13:07"
    },
    {
        "id": 10,
        "year": "2017",
        "month": "09",
        "updated_at": "2017-09-23 19:05:52"
    },
    {
        "id": 4,
        "year": "2017",
        "month": "09",
        "updated_at": "2017-09-18 17:32:49"
    },
    {
        "id": 3,
        "year": "2017",
        "month": "07",
        "updated_at": "2017-07-22 17:34:20"
    },
    {
        "id": 6,
        "year": "2017",
        "month": "07",
        "updated_at": "2017-07-02 17:28:49"
    },
    {
        "id": 12,
        "year": "2017",
        "month": "06",
        "updated_at": "2017-06-15 15:31:18"
    },
    {
        "id": 11,
        "year": "2017",
        "month": "06",
        "updated_at": "2017-06-11 15:32:16"
    }
]

期望所得数据如下

    "2018": {
        "03": [{
            "id": 15,
            "updated_at": "2018-03-01"
        }],
        "02": [{
            "id": 14,
            "updated_at": "2018-02-24"
        }]
    },
    "2017": {
        "12": [{
            "id": 13,
            "updated_at": "2017-12-02"
        }],
        "11": [{
            "id": 5,
            "updated_at": "2017-11-10"
