forEach如何将多个数据保存到MondoDB中

const mongoose = require('mongoose');

// 连接到MongoDB数据库
mongoose.connect('mongodb://localhost/mydatabase', { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => {
    console.log('Connected to MongoDB');
  })
  .catch((error) => {
    console.error('Failed to connect to MongoDB', error);
  });

// 定义数据模型
const dataSchema = new mongoose.Schema({
  name: String,
  age: Number,
});

const DataModel = mongoose.model('Data', dataSchema);

// 要保存的多个数据
const dataArray = [
  { name: 'John', age: 25 },
  { name: 'Jane', age: 30 },
  { name: 'Bob', age: 35 },
];

// 使用forEach保存数据到MongoDB
dataArray.forEach((data) => {
  const newData = new DataModel(data);
  newData.save()
    .then(() => {
      console.log('Data saved successfully');
    })
    .catch((error) => {
      console.error('Failed to save data', error);
    });
});
