使用lodash通过属性连接对象数组

var users = [
  { name: 'Alice', age: 25, gender: 'female' },
  { name: 'Bob', age: 30, gender: 'male' },
  { name: 'Charlie', age: 35, gender: 'male' },
  { name: 'Diana', age: 40, gender: 'female' }
];

var groupedUsers = _.groupBy(users, 'gender');

console.log(groupedUsers);
// 输出：
// {
//   female: [
//     { name: 'Alice', age: 25, gender: 'female' },
//     { name: 'Diana', age: 40, gender: 'female' }
//   ],
//   male: [
//     { name: 'Bob', age: 30, gender: 'male' },
//     { name: 'Charlie', age: 35, gender: 'male' }
//   ]
// }
