__proto__.printName = function () { return 'Oops' }; p1.printName() // "Oops" p2.printName() // "Oops" var p3 = new Point(4,2); p3.printName() // "Oops" 上面代码在p1的原型上添加了一个printName()方法,由于p1的原型就是p2的原型,因此p2也可以调用这个方法。而且,此后新建的...
log(#foo in this); // 报错 } } 上面示例中,私有属性#foo没有声明,就直接用于in运算符的判断,导致报错。 静态块 静态属性的一个问题是,如果它有初始化逻辑,这个逻辑要么写在类的外部,要么写在constructor()方法里面。 class C { static x = 234; static y; static z; } try { const obj = do...
