如何在typescript中对具有属性的对象数组进行分组？

interface Person {
  name: string;
  age: number;
  gender: string;
}

const people: Person[] = [
  { name: 'Alice', age: 25, gender: 'female' },
  { name: 'Bob', age: 30, gender: 'male' },
  { name: 'Charlie', age: 35, gender: 'male' },
  { name: 'Diana', age: 28, gender: 'female' },
  { name: 'Eve', age: 32, gender: 'female' },
];

const groupByGender = people.reduce((acc: { [key: string]: Person[] }, person: Person) => {
  if (!acc[person.gender]) {
    acc[person.gender] = [];
  }
  acc[person.gender].push(person);
  return acc;
}, {});

console.log(groupByGender);
