有关交换对象的键/值的问题

Question

我想将 Jacob 的键/值内容与 Guillermo 的键/值内容交换

我能够将吉列尔莫换成雅各布，但不能反过来。

这是我的代码，只正确一半：

let students = {
jacob: {
classes: ["math", "chemistry", "english"],
grade: 11,
age: 16,
},
guillermo: {
classes: ["history", "math", "physics"],
grade: 12,
age: 17,
},
};
let temp = students.jacob;
students.guillermo = temp;
let temp1 = students.guillermo;
students.jacob = temp1;
console.log(students)

Answer 1

您需要在重新分配之前复制

let students = {
jacob: {
classes: ["math", "chemistry", "english"],
grade: 11,
age: 16,
},
guillermo: {
classes: ["history", "math", "physics"],
grade: 12,
age: 17,
},
};
let temp = students.jacob;
let temp1 = students.guillermo;
students.guillermo = temp;
students.jacob = temp1;
console.log(students)
