    // {}={}

    // 2.属性名相同的完成赋值
    // const { age, username } = { username: 'Alex', age: '18' };
    // const { age: age, username: usernaem } = { username: 'Alex', age: '18' };
    // console.log(age, username);

    // 取别名
    const { age: age, username: uname } = { username: 'Alex', age: '18' };
    console.log(age, uname);
