Typescript -根据多个值对数组中的对象进行分组和过滤

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' },
];

// 根据性别分组
const groupedByGender: { [key: string]: Person[] } = people.reduce((acc, person) => {
  if (!acc[person.gender]) {
    acc[person.gender] = [];
  }
  acc[person.gender].push(person);
  return acc;
}, {});

console.log(groupedByGender);

// 过滤年龄大于30的人
const filteredByAge: Person[] = people.filter(person => person.age > 30);

console.log(filteredByAge);
