我有一个日期数组,并一直使用map函数迭代它,但我无法弄清楚将它们转换为整数的JavaScript代码.

这是日期数组:

var dates_as_int = [
    "2016-07-19T20:23:01.804Z",
    "2016-07-20T15:43:54.776Z",
    "2016-07-22T14:53:38.634Z",
    "2016-07-25T14:39:34.527Z"

    "amount": 1000.33

    {
    "date": "2017-09-08",
    "description": "DD from my employer1",
    "amount": 2000.33
    },
    {
    "date": "2017-09-09",
    "description": "DD from my employer1",
    "amount": 2000.33
    },
    {
    "date": "2017-09-10",
    "description": "DD from my employer1",
    "amount": 2000.33
