ts for循环示例

interface IUser {
  name: string;
  age: number;
}

const user: IUser = {
  name: 'John',
  age: 30,
};

// 将对象转换为键值对数组，然后使用 for...of 遍历
for (const [key, value] of Object.entries(user)) {
  console.log(key, value);
}

// 使用 for...in 遍历对象的属性
for (let _key in user) {
  const key = _key as keyof IUser;
  console.log(key, user[key]);
}
