instanceof是用来判断对象是否隶属于某个类(或某个类的子类)的运算符,和typeof一样重要,用来作类型校验 objinstanceofClass classTestextendsArray{}console.log(newTestinstanceofArray);//true,是Array的子类console.log(newTestinstanceofObject);//true 默认情况下会考虑其原型链,如上代码还可以隶属于Object,但实...
Object.setPrototypeOf(obj, Document.prototype) console.log(obj.__proto__)//Document {…}//8、获取自身所有属性console.log(Object.getOwnPropertyNames(document))//['location']//9、获取自身所有符号属性console.log(Object.getOwnPropertySymbols(Document.prototype))//[Symbol(Symbol.toStringTag), Symbol(Sy...

const proxy = new Proxy(dong, handler) for (const key of Object.keys(proxy)) { console.log(key, proxy[key]) } 确实,这里只打印了公有属性的方法,而下划线开头的那两个属性没有打印。 我们基于 _prop 这种命名规范实现了真正的私有属性! 再调用下方法试试: 咋是undefined 了? 因为proxy.hello 方...
Object.create(prototype, [propertiesObject]); 第一个参数prototype是创建的对象所对应的prototype,相当于使用function创建时中的prototype属性对象,创建出来的object对象实例可以直接调用。 第二个参数propertiesObject为属性描述对象,是可选参数,用于描述所创建对象的自身属性。属性描述对象是object类型对象,它里面的属性名...
二、class类与原型的关系 class类本质上就是一个函数,自身指向的就是构造函数,看代码: console.log(typeof Cat);// function console.log(Cat.prototype.constructor ===Cat);//true class类是构造函数的另一种写法,仍然存在prototype方法 console.log(Cat.prototype);//object ...
