前言先直接上一个原型链图以便讲解:
图中Parent是构造函数，p1是通过Parent实例化出来的一个对象。
想要弄清楚原型和原型链，这几个属性必须要搞清楚，__proto__、prototype、 constructor。JavaScript中一切皆对象，函数也是对象。函数中有个特殊的函数——构造函数，任何函数都可以作为构造函数，但是并不能将任意函数叫做构造函数，只有当一个函数通过new关键字

前言在本文中，我们的目标是创建和发布一个无需更改代码即可在客户端和服务器端应用程序中使用的库。
我们需要满足以下用例：
该库是用 ES6+ 编写的，使用 import 和 export 关键字
该库可以与 <script>标签一起使用
该库可用于使用现代打包器的 Web 应用程序。
该库可用于Node应用程序。
从技术上讲，这意味着库需要在以下上下文中工作：

前言为啥使用supervisor，因为最近给我的API服务增加了一个定时任务，需要后台一直运行一条命令行，当关掉这个命令行时任务就不会跑了，各种搜索，定位到supervisor能解决这个问题。于是了解了一下，发现Supervisor还能解决Django项目不能自动启动的问题。Supervisor是用Python开发的一套通用的进程管理程序，能将一个普通的命令行进程变为后台daemon，并监控进程状

前言所谓魔改，就是与主题不同，一旦主题已经被采用或者被实现，则会被划掉，而且魔改初心是使用无侵入式的方式修改——即不修改源码，而是使用注入器的方式。这样的话主题升级比较容易！
背景固定效果如背景所示，这种效果贯穿着整个博客。具体做法如下：使用注入器(如果没有injector.js文件，则在scripts文件夹下新建injector.js)，在injector.js中写下这些代码。

创建型设计模式创建型设计模式包括：单例模式、工厂模式、建造者模式、原型模式。它主要解决对象的创建问题，封装复杂的创建过程，解耦对象的创建代码和使用代码。
单例模式单例模式用来创建全局唯一的对象。一个类只允许创建一个对象（或者叫实例），那这个类就是一个单例类，这种设计模式就叫作单例模式。单例有几种经典的实现方式，它们分别是：
