What makes the Singleton is the global access to the instance (generally throughMySingleton.getInstance()) as we don't (at least in static languages) callnew MySingleton()directly. This is however possible in JavaScript. In the GoF book, theapplicabilityof the Singleton pattern is described as...
设计模式(Design pattern)是一套被反复使用、多数人知晓的、经过分类编目的、代码设计经验的总结。使用设计模式是为了可重用代码、让代码更容易被他人理解、保证代码可靠性。 毫无疑问,设计模式于己于他人于系统都是多赢的,设计模式使代码编制真正工程化,设计模式是软件工程的基石,如同大厦的一块块砖石一样。项目中合...
通过将你的代码放置在一个单一对象中,你想创建一个能被其他人使用而不必担心重写他们全局变量的API迈出了一大步。这是迈向一个高级javascript开发者的第一步。
