我怎么读这样的JSON结构？

{
  "name": "John",
  "age": 30,
  "city": "New York",
  "pets": [
    {
      "name": "Max",
      "species": "dog"
    },
    {
      "name": "Lucy",
      "species": "cat"
    }
  ]
}

const jsonStr = '{"name":"John","age":30,"city":"New York","pets":[{"name":"Max","species":"dog"},{"name":"Lucy","species":"cat"}]}';

const jsonObj = JSON.parse(jsonStr);

console.log(jsonObj.name); // 输出：John
console.log(jsonObj.age); // 输出：30
console.log(jsonObj.city); // 输出：New York
console.log(jsonObj.pets[0].name); // 输出：Max
console.log(jsonObj.pets[1].species); // 输出：cat
