获取对象数组中每一天的最新日期？

Question

我有一个根据日期/时间排序的对象数组，我必须用每个日期的最新数据形成一个对象数组？我正在使用 for 循环获得解决方案，但我需要使用 es6 及更高版本，请帮助我提供更好、更高级的解决方案。

var array = [
  {
    "id": 1,
    "date": "2016-01-15T16:18:44.258843Z",
    "status": "NEW",
    "request": 4
  },
 {
    "id": 2,
    "date": "2016-01-15T18:18:44.258843Z",
    "status": "NEW",
    "request": 4
  },
 {
    "id": 3,
    "date": "2016-01-15T20:18:44.258843Z",
    "status": "NEW",
    "request": 4
  },
  {
    "id": 4,
    "date": "2016-01-19T16:18:44.258843Z",
    "status": "STD",
    "request": 4
  },
  {
    "id": 6,
    "date": "2016-01-23T17:18:44.258843Z",
    "status": "FOR",
    "request": 4
  },
{
    "id": 5,
    "date": "2016-01-23T16:18:44.258843Z",
    "status": "FOR",
    "request": 4
  }]
const list = filter(array, el => (el.date));
   latestDate = list[0]?.date.slice(0, 10);
   latestResponse.push(res[0]);
 for (let i = array.length - 1; i > 0; i--) {
      if (this.latestDate !== array[i].date.slice(0, 10)) {
      latestDate = (array[i].date).slice(0, 10);
        latestResponse.push(res[i]);
      }
    }

预期输出

var array = [
     {
        "id": 3,
        "date": "2016-01-15T20:18:44.258843Z",
        "status": "NEW",
        "request": 4
      },
      {
        "id": 4,
        "date": "2016-01-19T16:18:44.258843Z",
        "status": "STD",
        "request": 4
      },
    {
        "id": 5,
        "date": "2016-01-23T17:18:44.258843Z",
        "status": "FOR",
        "request": 4
      }]

Answer 1

const latestResponse = [];
    const list = filter(res, el => (el.date));
    let latestDate = moment(list[0]?.date).format("DD/MM/YYYY");
    [...res].reverse().filter(el => {
      if (latestDate !== moment(el.date).format("DD/MM/YYYY")) {
        latestDate = moment(el.date).format("DD/MM/YYYY");
        latestResponse.push(el);
      }
    })

使用moment来格式化日期，并使用filter来生成新数组
