盘点JavaScript中getter()和setter()函数的使用

例：有一个具有 name和 surname属性的对象 user：添加一个 fullName属性，该属性值应该为 "John Smith"。...当然，不想复制粘贴已有的信息，因此可以使用访问器来实现： let user = { name: "John", surname: "Smith", get fullName() {...return `${this.name} ${this.surname}`; } }; alert(user.fullName); // John Smith 从外表看，访问器属性看起来就像一个普通属性...: "Smith", get fullName() { return `${this.name} ${this.surname}`; }, set fullName(value) {...Cooper"; alert(user.name); // Alice alert(user.surname); // Cooper 现在，就有一个“虚拟”属性。

盘点JavaScript中解构赋值，数组解构常用的数组操作

alert(surname); // Kantor 现在就可以针对这些变量进行操作，而不是针对原来的数组元素。...当与 split 函数（或其他返回值是数组的函数）结合使用时，看起来就更优雅了： let [firstName, surname] = "Ilya Kantor".split(' '); 1....let [firstName, surname] = []; alert(firstName); // undefined alert(surname); // undefined 如果想要一个“默认..., surname = prompt('surname?')]...= ["Julius"]; alert(name); // Julius（来自数组） alert(surname); // 输入的值二、对象解构解构赋值同样适用于对象。
