如何使用数组从对象数组中拉取值

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

const names = people.map(person => person.name);
console.log(names); // 输出: ['Alice', 'Bob', 'Charlie']

const names = people.map(person => {
  // 忘记返回值
  person.name;
});

const names = people.map(person => {
  return person.name; // 添加返回值
});

const names = people.map(person => {
  return person.name || 'Unknown'; // 如果 name 不存在，则返回 'Unknown'
});
