JavaScript 数组处理

Question

var arr = ['aaa', 'ccc']
var data = {
      aaa: [{count: 31, date: '202010'}, {count: 32, date: '202011'}, {count: 33, date: '202012'}, {count: 34, date: '202013'}],
      bbb: [{count: 10, date: '202010'}, {count: 12, date: '202011'}, {count: 13, date: '202012'}, {count: 14, date: '202013'}],
      ccc: [{count: 21, date: '202010'}, {count: 22, date: '202011'}, {count: 23, date: '202012'}, {count: 24, date: '202013'}],
    }
最后要的结果
    // arr = [
    //   {aaa:31, ccc:21, date: 202010},
    //   {aaa:32, ccc:22, date: 202011},
    //   {aaa:33, ccc:23, date: 202012},
    //   {aaa:34, ccc:24, date: 202013}
    // ]

测试:

var arr = ['aaa', 'ccc']
var data = {
      aaa: [{count: 31, date: '202010'}, {count: 32, date: '202011'}, {count: 33, date: '202012'}, {count: 34, date: '202013'}],
      bbb: [{count: 10, date: '202010'}, {count: 12, date: '202011'}, {count: 13, date: '202012'}, {count: 14, date: '202013'}],
      ccc: [{count: 21, date: '202010'}, {count: 22, date: '202011'}, {count: 23, date: '202012'}, {count: 24, date: '202013'}],
    }
console.log(JSON.stringify(getResult(data, arr), null, 2))

输出：

[
  {
    "date": "202010",
    "aaa": 31,
    "ccc": 21
  },
  {
    "date": "202011",
    "aaa": 32,
    "ccc": 22
  },
  {
    "date": "202012",
    "aaa": 33,
    "ccc": 23
  },
  {
    "date": "202013",
    "aaa": 34,
    "ccc": 24
  }
]
