账单列表如何将年份月份一样的排在一起

Question

array:[{

                "amount":5000,

                "goodsInfo":"翡翠城租金",

                "tradeTime":"2019-04-20"

            },

            {

                "amount":1200,

                "goodsInfo":"五联西苑租金",

                "tradeTime":"2019-04-25"

            },

            {

                "amount":200,

                "goodsInfo":"爱与家宾馆",

                "tradeTime":"2019-04-30"

            },

            {

                "amount":3800,

                "goodsInfo":"丁香花园",

                "tradeTime":"2019-05-20"

            },

            {

                "amount":2500,

                "goodsInfo":"滨兴小区",

                "tradeTime":"2019-05-28"

            },

            {

                "amount":2800,

                "goodsInfo":"滨苑小区",

                "tradeTime":"2019-06-08"

            }]

我从后台拿到一组数据是如果这样的，我要怎么提取出年份月份一样的，将其排在一起变成像下面那个数组，后面有效果图

newArray:[

                {

                    "tradeTime":[

                        {

                            "amount":5000,

                            "goodsInfo":"翡翠城租金",

                            "tradeTime":"2019-04-20"

                        },

                        {

                            "amount":1200,

                            "goodsInfo":"五联西苑租金",

                        }

                    ]

                },

                {

                    "tradeTime":[

Answer 2

把时间转化成时间戳，按照时间戳进行排序

var arr = [{

//可以稍微改造一下
console.log(dest)
