继承inheritance constructor pattern for custom types: methods must be defined inside the constructor,so there's no function reuse. 构造函数模式存在的问题--方法都在构造函数中定义,因此函数复用就无从谈起了。 2017-09-15补充,终于看到原来也看到
Uberproto is a simple base object that adds some sugar to ECMAScript 5 style object inheritance in JavaScript. Here is what it can do in a nutshell: Easily extend objects Initialization methods Super methods Mixins Method proxies With a small footprint (about 0.5Kb minified) and an easy to...
Having coded it up, I'm not that happy with it. It seems as if I'm tryingwaytoo hard to force a class inheritance model approach to what are, after all, very simple objects. It would work equally well without the call toObject.createin there. I'll ignore my doubts for the moment ...
// Classical inheritance has nothing on this.// No parent/child coupling. No deep inheritance hierarchies.// Just good, clean code reusability.const Bar = stampit(Defaults, Availability, Membership);// Create an object instanceconst myBar = Bar({name: 'Moe\'s'});// Silly, but proves tha...

2006年,Douglas Grockford 写了一篇文章:《JavaScript 中的原型式继承》(”Prototypal Inheritance in JavaScript“)。这篇文章介绍了一种不涉及严格意义上构造函数的继承方法。他的出发点是即使不自定义类型也可以通过原型继承对象之间的信息共享。文章最终给出了一个函数: ...

What's in a name? 原型链条继承机制? 在JS, 我们不进行从一个对象(类)到另一个对象(instance)的复制行为。 我们连接双方。 作者认为prototypal inheritance这个词对理解JavaScript的机制,坏处多于好处! inheritance暗示了复制操作, 但JS没有复制对象功能。
