使用lodash按多个关键点对对象进行分组

const _ = require('lodash');

const data = [
  { name: 'Alice', age: 25, gender: 'female' },
  { name: 'Bob', age: 30, gender: 'male' },
  { name: 'Charlie', age: 25, gender: 'male' },
  { name: 'Dave', age: 30, gender: 'male' },
  { name: 'Eve', age: 25, gender: 'female' }
];

const groupedData = _.groupBy(data, ['age', 'gender']);

console.log(groupedData);

{
  '25': {
    female: [
      { name: 'Alice', age: 25, gender: 'female' },
      { name: 'Eve', age: 25, gender: 'female' }
    ],
    male: [
      { name: 'Charlie', age: 25, gender: 'male' }
    ]
  },
  '30': {
    male: [
      { name: 'Bob', age: 30, gender: 'male' },
      { name: 'Dave', age: 30, gender: 'male' }
    ]
  }
}
