老师你能不能看一下我这样理解代表正不正确？

const set = (name, value, { maxAge, domain, path, secure } = {}) => {

//{ maxAge, domain, path, secure } = {}

//1.这里是对象属性的简介表示法默认值是undefined和对象的结构赋值相当于

//{maxAge: maxAge=undefined, domain: domain=undefined, path: path=undefined, secure: secure=undefined} ={在这里是调用方法时传入的对象}

  let cookieText = `${encodeURIComponent(name)}=${encodeURIComponent(value)}`;

  if (typeof maxAge === 'number') {

    cookieText += `; max-age=${maxAge}`;

//2.是不是可以把max-age=${maxAge}写成 max-age=[maxAge]，因为这里maxage是一个变量

  }

  if (domain) {

    cookieText += `; domain=${domain}`;

  }

  if (path) {

    cookieText += `; path=${path}`;

  }

  if (secure) {

    cookieText += `; secure`;

  }

  document.cookie = cookieText;

  // document.cookie='username=alex; max-age=5; domain='

};

set('sex', 'male', {

      maxAge: 30 * 24 * 3600

//3.const set = ('sex', 'male', { maxAge: maxAge=undefined, domain: domain=undefined, path: path=undefined, secure: secure=undefined} = {maxAge: 30 * 24 * 3600}) 

​});
