如何在Mongoose模式中描述对象来存储任何属性，包括已定义的属性？

const mongoose = require('mongoose');

const userSchema = new mongoose.Schema({
  name: String,
  age: Number,
  otherProps: mongoose.Schema.Types.Mixed
});

const User = mongoose.model('User', userSchema);

const newUser = new User({
  name: 'John',
  age: 25,
  otherProps: {
    interests: ['music', 'sports'],
    address: '123 Main St'
  }
});

newUser.save()
  .then(() => {
    console.log('User saved successfully');
  })
  .catch((error) => {
    console.error('Error saving user:', error);
  });
