如何使用javascript读取嵌套属性并推送到数组？

function pushNestedProperties(obj, result = [], prefix = '') {
  for (let key in obj) {
    if (typeof obj[key] === 'object' && obj[key] !== null) {
      pushNestedProperties(obj[key], result, prefix + key + '.');
    } else {
      result.push(prefix + key + ': ' + obj[key]);
    }
  }
  return result;
}

// 示例对象
const obj = {
  name: 'John',
  age: 30,
  address: {
    street: '123 Main St',
    city: 'New York',
    country: 'USA'
  },
  hobbies: ['reading', 'coding']
};

// 调用函数并打印结果
const result = pushNestedProperties(obj);
console.log(result);

[
  "name: John",
  "age: 30",
  "address.street: 123 Main St",
  "address.city: New York",
  "address.country: USA",
  "hobbies.0: reading",
  "hobbies.1: coding"
]
