任何人都可以用传播运算符解释这里发生了什么

Question

下面的代码给出了我想要的输出，但我需要了解更多。任何人都可以用传播运算符解释这里发生了什么，

 const myObject = {
      "employeeid": "160915848",
      "firstName": "tet",
      "lastName": "test",
      "email": "test@email.com",
      "country": "Brasil",
      "currentIndustry": "aaaaaaaaaaaaa",
      "otherIndustry": "aaaaaaaaaaaaa",
      "currentOrganization": "test",
      "salary": "1234567"
    };
    const {otherIndustry,currentOrganization, ...otherIndustry2} = myObject;
    console.log(otherIndustry2);

Output:

{
  "employeeid": "160915848",
  "firstName": "tet",
  "lastName": "test",
  "email": "test@email.com",
  "country": "Brasil",
  "currentIndustry": "aaaaaaaaaaaaa",
  "salary": "1234567"
};

Answer 1

这更像是一个对象解构赋值问题。

所以这一行const {otherIndustry,currentOrganization, ...otherIndustry2} = myObject;是一个对象解构语句，它首先将otherIndustry和currentOrganization的值赋给同名变量，其余的值, 它们都作为对象分配给 otherIndustry2

参考：destructuring assignment
