返回所有属性为长度的嵌套对象文字？

function findNestedObjectWithLength(obj) {
  let result = {};

  for (let key in obj) {
    if (typeof obj[key] === 'string' && obj[key].length === key.length) {
      result[key] = obj[key];
    } else if (typeof obj[key] === 'object') {
      const nestedResult = findNestedObjectWithLength(obj[key]);
      if (Object.keys(nestedResult).length > 0) {
        result[key] = nestedResult;
      }
    }
  }

  return result;
}

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

// 调用函数并输出结果
const result = findNestedObjectWithLength(obj);
console.log(result);
