如何使用lodash对对象中的数组数据进行计数分组

const _ = require('lodash');

const data = [
  { name: 'Alice', age: 20 },
  { name: 'Bob', age: 25 },
  { name: 'Alice', age: 30 },
  { name: 'Bob', age: 35 },
  { name: 'Alice', age: 40 }
];

const groupedData = _.groupBy(data, 'name');
console.log(groupedData);

{
  'Alice': [
    { name: 'Alice', age: 20 },
    { name: 'Alice', age: 30 },
    { name: 'Alice', age: 40 }
  ],
  'Bob': [
    { name: 'Bob', age: 25 },
    { name: 'Bob', age: 35 }
  ]
}

const _ = require('lodash');

const data = ['apple', 'banana', 'apple', 'orange', 'banana', 'apple'];

const countedData = _.countBy(data);
console.log(countedData);

{
  'apple': 3,
  'banana': 2,
  'orange': 1
}
