如何在Mongoose列表的顶部保存数据？

const mongoose = require('mongoose');

const itemSchema = new mongoose.Schema({
  // 定义数据结构和属性
  name: String,
  description: String,
  // ...
});

const Item = mongoose.model('Item', itemSchema);

const newItem = new Item({
  name: 'Example',
  description: 'This is an example item',
  // ...
});

newItem.save()
  .then(() => {
    console.log('Data saved successfully');
  })
  .catch((error) => {
    console.error('Error saving data:', error);
  });

const newData = [
  {
    name: 'Example 1',
    description: 'This is example 1',
    // ...
  },
  {
    name: 'Example 2',
    description: 'This is example 2',
    // ...
  },
  // ...
];

Item.insertMany(newData)
  .then(() => {
    console.log('Data saved successfully');
    // 将新插入的数据移动到列表的顶部
    Item.find().sort({ _id: -1 }).exec((error, items) => {
      if (error) {
        console.error('Error retrieving data:', error);
      } else {
        const topItem = items[0];
        items.splice(items.indexOf(topItem), 1);
        items.unshift(topItem);
        console.log('Data order updated');
      }
    });
  })
  .catch((error) => {
    console.error('Error saving data:', error);
  });
