以日期为关键字，使用lodash和moment进行对象分组

const _ = require('lodash');
const moment = require('moment');

const objects = [
  { id: 1, date: '2022-01-01', name: 'Object 1' },
  { id: 2, date: '2022-01-01', name: 'Object 2' },
  { id: 3, date: '2022-01-02', name: 'Object 3' },
  { id: 4, date: '2022-01-02', name: 'Object 4' },
  { id: 5, date: '2022-01-03', name: 'Object 5' },
];

const groupedObjects = _.groupBy(objects, (obj) => moment(obj.date).format('YYYY-MM-DD'));

_.forEach(groupedObjects, (group, key) => {
  console.log(`日期：${key}`);
  console.log('分组对象：', group);
});
