The latest version of the .NET Runtime enables you to instantiate an object without having to repeat the type name (target-typed constructor invocation). For example, the following code will create a new instance of the Random class: c# Copy Random dice = new(); The intention is to si...

ES6 class 出现之前,个人认为比较完美的继承是使用原型链加组合的继承方式,以前研究原型继承写的代码在这:prototypeExtends。这里不展开讲 javascript 的继承,那会又是一个巨坑。 组合继承其实很好理解,这个组合指的是子类的实例属性组合了父类的实例属性,看代码: ...
初次时指向Class超级父类 var _super = this.prototype; // Instantiate a base class (but only create the instance, // don't run the init constructor) //开关 用来使原型赋值时不调用真正的构成流程 initializing = true; var prototype = new this(); initializing = false; // Copy the properties...
应该使用prototype 还有继承的写法：function extend(baseclass, subclass) {function T() {}T.prototype = baseclass.prototype;subclass.prototype = new T();subclass.prototype.constructor = subclass;} var Writeable = function(options) { this.filename = "zhanghao"; this.filepath = "...
