使用嵌套数组Javascript遍历Json对象

function traverseJson(jsonObj) {
  for (var key in jsonObj) {
    if (jsonObj.hasOwnProperty(key)) {
      var value = jsonObj[key];
      if (typeof value === 'object') {
        // 如果属性值是一个对象，则递归调用traverseJson函数
        traverseJson(value);
      } else {
        // 如果属性值不是一个对象，则直接输出属性名和属性值
        console.log(key + ': ' + value);
      }
    }
  }
}

var jsonObj = {
  "name": "John",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "New York",
    "state": "NY"
  },
  "hobbies": ["reading", "coding", "traveling"]
};

traverseJson(jsonObj);
