var person = {
          course1:{Name:"xxx", day:"mon", time:"2am-6pm"},
          course2:{Name:"yyy", day:"tue", time:"7am-9pm"},
          course3:{Name:"zzz", day:"tue", time:"2am-6pm"},
          course4:{Name:"aaa", day:"wed", time:"2am-6pm"},
          course5:{Name:"bbb", day:"thu", time:"2am-6pm"},
          course6:{Name:"ccc", day:"mon", time:"2am-6pm"} 
        };

任何人都可以展示如何循环和迭代这个人对象并交换 course1 和 course2 对象值（名称，日期，时间）并做一些事情，替换它并再次交换 course1 和 course3 做一些事情等等......

您可以使用Object.keys来获取所有键数组，然后您可以对其进行迭代。

类似的东西：

const person = {
  course1: {
    Name: "xxx",
    day: "mon",
    time: "2am-6pm"
  },
  course2: {
    Name: "yyy",
    day: "tue",
    time: "7am-9pm"
  },
  course3: {
    Name: "zzz",
    day: "tue",
    time: "2am-6pm"
  },
  course4: {
    Name: "aaa",
    day: "wed",
    time: "2am-6pm"
  },
  course5: {
    Name: "bbb",
    day: "thu",
    time: "2am-6pm"
  },
  course6: {
    Name: "ccc",
    day: "mon",
    time: "2am-6pm"
  }
};

Object.keys(person).forEach((key) => {
  const course = person[key];
  // Do your logic here...
});
