Question

如何编写适当的函数以将Calendar_ID忙碌数组从响应匹配到客户端日历数组项？

这是我从服务器收到的代码：

初始化对象nr 1

response = {
  calendars: {
    calendarID_1: {
      busy: [{},{}]
    },
    calendarID_2: {
      busy: [{},{}]
    },
  },
  ...
}

这是我需要合并数据的代码：

初始化arr nr 2

clients = [
  {
    name: clientName,
    calendars: ["calendarID_1", "calendarID_2"]
  },
  ...
]

这是迭代函数之后的样子：

输出arr应该是

clients = [
  {
    name: clientName,
    calendars: {
      calendarID_1: {
        busy: [{}, {}]
      },
      calendarID_2: {
        busy: [{}, {}]
      },
    }
  },
  ...
]

我的尝试是：

for (const calendar in response.calendars) {
    for (const client in clients) {
        clients[client].calendars.reduce((acc, cur) => {
            if (cur === calendar) {
                 acc[cur] = response.calendars[calendar];
            }
        });
    }
}

// Input:
const response = {
  calendars: {
    calendarID_1: {
      content: "of calendar 1",
    },
    calendarID_2: {
      content: "of calendar 2",
    },
    calendarID_3: {
      content: "of calendar 3",
    },
  },
}

const clients = [
  {
    name: "first",
    calendars: ["calendarID_1", "calendarID_2"]
  },
  {
    name: "second",
    calendars: ["calendarID_3"]
  },
    
]



// Solution:

const result = clients.map(client => ({
  ...client,
  calendars: Object.fromEntries(
    client.calendars.map(id => ([ id, response.calendars[id] ]))
  ),
}));

console.log(result);

这将映射到一个新的客户端数组，传播先前的客户端，该客户端基本上会浅抄整个数组，然后获取客户端日历的ID，在响应中查找它们，并从中创建一个新对象。这是客户日历ID的数量的O（n）。

如何将数组元素从一个对象匹配到另一个对象？
