在JavaScript中查询对象数组，根据多个条件进行匹配

// 假设有一个对象数组，包含多个人员信息
const people = [
  { name: 'Alice', age: 25, city: 'New York' },
  { name: 'Bob', age: 30, city: 'Los Angeles' },
  { name: 'Charlie', age: 35, city: 'San Francisco' },
  { name: 'Dave', age: 40, city: 'New York' }
];

// 定义多个条件
const conditions = {
  age: 30,
  city: 'New York'
};

// 使用filter()方法进行匹配
const filteredPeople = people.filter(person => {
  for (let key in conditions) {
    if (person[key] !== conditions[key]) {
      return false;
    }
  }
  return true;
});

console.log(filteredPeople);
