我如何在预订系统中组织"Place“模型的可用日期？(mongoose和mongoDB)

const mongoose = require('mongoose');

const placeSchema = new mongoose.Schema({
  name: String,
  availableDates: [Date]
});

const Place = mongoose.model('Place', placeSchema);

const place = new Place({
  name: '某地点',
  availableDates: [new Date('2022-01-01'), new Date('2022-01-02')]
});

place.save();

const targetDate = new Date('2022-01-01');

Place.findOne({ availableDates: targetDate }, (err, place) => {
  if (err) {
    console.error(err);
  } else {
    if (place) {
      console.log('该日期可用');
    } else {
      console.log('该日期不可用');
    }
  }
});

Place.find({}, 'availableDates', (err, places) => {
  if (err) {
    console.error(err);
  } else {
    const allAvailableDates = places.reduce((dates, place) => {
      return dates.concat(place.availableDates);
    }, []);
    console.log(allAvailableDates);
  }
});
