以最干净/最有效的方式选择具有最小键值的对象

function getMinKeyValueObject(obj) {
  let minKeyValue = Infinity;
  let minKeyValueObject = {};

  for (let key in obj) {
    if (obj.hasOwnProperty(key)) {
      if (key < minKeyValue) {
        minKeyValue = key;
      }
    }
  }

  for (let key in obj) {
    if (obj.hasOwnProperty(key)) {
      if (key === minKeyValue) {
        minKeyValueObject = obj[key];
      }
    }
  }

  return minKeyValueObject;
}

// 示例对象
const exampleObject = {
  2: { name: 'Object 2' },
  1: { name: 'Object 1' },
  4: { name: 'Object 4' },
  3: { name: 'Object 3' }
};

// 获取具有最小键值的对象
const minKeyValueObject = getMinKeyValueObject(exampleObject);

console.log(minKeyValueObject); // 输出：{ name: 'Object 1' }
