如何访问JSON中的嵌套对象？

{
  "person": {
    "name": "John",
    "age": 30,
    "address": {
      "city": "New York",
      "country": "USA"
    }
  }
}

const json = {
  "person": {
    "name": "John",
    "age": 30,
    "address": {
      "city": "New York",
      "country": "USA"
    }
  }
};

const name = json.person.name;
console.log(name); // 输出：John

{
  "employees": [
    {
      "name": "John",
      "age": 30
    },
    {
      "name": "Jane",
      "age": 25
    }
  ]
}

const json = {
  "employees": [
    {
      "name": "John",
      "age": 30
    },
    {
      "name": "Jane",
      "age": 25
    }
  ]
};

const name = json.employees[0].name;
console.log(name); // 输出：John
