根据值列表过滤对象数组

// 原始数据
const people = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 30 },
  { name: 'Charlie', age: 35 },
  { name: 'David', age: 40 }
];

// 需要过滤的年龄列表
const agesToFilter = [25, 35];

// 过滤函数
const filteredPeople = people.filter(person => agesToFilter.includes(person.age));

console.log(filteredPeople);
// 输出: [{ name: 'Alice', age: 25 }, { name: 'Charlie', age: 35 }]

const complexFilter = people.filter(person => {
  return person.age > 25 && person.name.startsWith('C');
});

console.log(complexFilter);
// 输出: [{ name: 'Charlie', age: 35 }]

const ageSet = new Set(agesToFilter);
const optimizedFilter = people.filter(person => ageSet.has(person.age));

console.log(optimizedFilter);
