如何在嵌套数组mongodb中插入数据？

const MongoClient = require('mongodb').MongoClient;

// 连接到MongoDB数据库
MongoClient.connect('mongodb://localhost:27017', (err, client) => {
  if (err) throw err;

  // 选择要插入数据的集合
  const db = client.db('mydb');
  const collection = db.collection('mycollection');

  // 构建要插入的数据
  const document = {
    name: 'John',
    hobbies: ['reading', 'music'],
    contacts: [
      { type: 'email', value: 'john@example.com' },
      { type: 'phone', value: '1234567890' }
    ]
  };

  // 插入数据
  collection.insertOne(document, (err, result) => {
    if (err) throw err;
    console.log('Data inserted successfully');
    client.close();
  });
});
