关于交换对象的键值的问题

Question

我想把Jacob的keyvalue内容和Guillermo的keyvalue内容互换。

我可以把Guillermo换成Jacob，但不能换成其他方式。

这是我的代码，只对了一半，我想把Jacob的keyvalue内容和Guillermo的keyvalue内容互换。

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

你需要复制之前，重新分配

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)
