如何使用promise和循环遍历mongoose集合

const mongoose = require('mongoose');

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);
  });

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

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

const getUsers = () => {
  return new Promise((resolve, reject) => {
    User.find()
      .then((users) => {
        resolve(users);
      })
      .catch((error) => {
        reject(error);
      });
  });
};

getUsers()
  .then((users) => {
    users.forEach((user) => {
      console.log(user);
    });
  })
  .catch((error) => {
    console.error(error);
  });
