根据匹配值从 2 个数组创建（多维？）数组

Question

我对如何基于其他 2 个数组正确制作数组有点困惑。

我有一个这样的数组：

let date = [1522303200000, 1522389600000, 1522476000000]

第二个数组看起来有点像这样：

let people = [
  {
    "id": 0,
    "name": "Sophia Mason",
    "biography": "Lorem ...",
    "availability": [
      {
        "date": 1522303200000,
        "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
      },
      {
        "date": 1522389600000,
        "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
      },
      {
        "date": 1522476000000,
        "times": ["10:00 am", "2:30 pm", "5:00 pm"]
      },
      {
        "date": 1522735200000,
        "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
      }
    ]
  },
  {
    "id": 1,
    "name": "Brandon Hampton",
    "biography": "Lorem ...",
    "availability": [
      {
        "date": 1522303200000,
        "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
      },
      {
        "date": 1522476000000,
        "times": ["10:00 am", "2:30 pm", "5:00 pm"]
      },
      {
        "date": 1522648800000,
        "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
      },
      {
        "date": 1522735200000,
        "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
      }
    ]
  }
]

我正在尝试创建一个数组，该数组将日期作为数组中每个索引的顶级，然后如果该日期有空的话，则在每一天的每个对应的人。我在想类似的事情：

let calendar = [
    [
      1522303200000,
      "photographers": [
        {
          "id": 0,
          "name": "Sophia Mason",
          "biography": "Lorem ...",
          "availability": [
            {
              "date": 1522303200000,
              "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
            },
            {
              "date": 1522389600000,
              "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
            },
            {
              "date": 1522476000000,
              "times": ["10:00 am", "2:30 pm", "5:00 pm"]
            },
            {
              "date": 1522735200000,
              "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
            }
          ]
        },
        {
          "id": 1,
          "name": "Brandon Hampton",
          "biography": "Lorem ...",
          "availability": [
            {
              "date": 1522303200000,
              "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
            },
            {
              "date": 1522476000000,
              "times": ["10:00 am", "2:30 pm", "5:00 pm"]
            },
            {
              "date": 1522648800000,
              "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
            },
            {
              "date": 1522735200000,
              "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
            }
          ]
        }
      ]
    ],
    [
      1522303200000,
      "photographers": [
        {
          "id": 0,
          "name": "Sophia Mason",
          "biography": "Lorem ...",
          "availability": [
            {
              "date": 1522303200000,
              "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
            },
            {
              "date": 1522389600000,
              "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
            },
            {
              "date": 1522476000000,
              "times": ["10:00 am", "2:30 pm", "5:00 pm"]
            },
            {
              "date": 1522735200000,
              "times": ["9:00 am", "2:30 pm", "5:00 pm", "6:00 pm"]
            }
          ]
        }
      ]
    ],
    ...
  ]

但我目前还在纠结如何解决这个问题。我可能已经看这个太久了，无法真正解决这个问题。

我查看了以下地方以获得一些想法：

Answer 1

这个函数

createCalendar(date, people) {
    const calendar = {};
    date.forEach(element => {
      calendar[element] = [];
      people.forEach(person => {
        if (person.availability.map(item => item.date).includes(element)) {
          calendar[element].push(person);
        }
      })
    })
    return calendar;
  }

创建与您所想的相似的数据结构。 calendar 是一个对象，其中每个键是一个 date，对应的值是一个数组，其中包含该日期可用的所有 people。
