如何使用匹配键值对数组从数组中拉取对象

const people = [
  { name: 'Alice', age: 25 },
  { name: 'Bob', age: 30 },
  { name: 'Charlie', age: 35 }
];

const key = 'age';
const value = 30;

const filteredPeople = people.filter(person => person[key] === value);

console.log(filteredPeople); // 输出: [{ name: 'Bob', age: 30 }]

const person = people.find(person => person[key] === value);

console.log(person); // 输出: { name: 'Bob', age: 30 }

let foundPerson;
people.some(person => {
  if (person[key] === value) {
    foundPerson = person;
    return true; // 找到匹配项后终止循环
  }
});

console.log(foundPerson); // 输出: { name: 'Bob', age: 30 }

let foundPerson;
for (let i = 0; i < people.length; i++) {
  if (people[i][key] === value) {
    foundPerson = people[i];
    break; // 找到匹配项后终止循环
  }
}

console.log(foundPerson); // 输出: { name: 'Bob', age: 30 }
