The Module Pattern Modules Modules are an integral piece of any robust application's architecture and typically help in keeping the units of code for a project both cleanly separated and organized. In JavaScript, there are several options for impleme…

The Observer Pattern The Observer is a design pattern where an object (known as a subject) maintains a list of objects depending on it (observers), automatically notifying them of any changes to state. When a subject needs to notify observers about s…

The Singleton Pattern The Singleton pattern is thus known because it restricts instantiation of a class to a single object. Classically, the Singleton pattern can be implemented by creating a class with a method that creates a new instance of the cla…

In classical object-oriented programming languages, a constructor is a special method used to initialize a newly created object once memory has been allocated for it. In JavaScript, as almost everything is an object, we're most often interested in ob…

The Mediator Design Pattern The Mediator is a behavioral design pattern in which objects, instead of communicating directly with each other, communicate only through a central message passing object (the Mediator). The Mediator pattern facilitates bo…

JavaScript is a class-less language, however classes can be simulated using functions. eg: // A car 'class' function Car(model) { this.model = model; this.color = 'silver'; this.year = '2012'; this.getInfo = function () { return this.model + ' ' + th…

JavaScript 为网站添加状态,这些状态可能是校验或者更复杂的行为像拖拽终止功能或者是异步的请求webserver (aka Ajax). 在过去的那些年里, JavaScript libraries变得越来越流行. 如果你面对着很多的工作计划,一个很明确的道理就是在网站变得越来越复杂的情况下每次修改‘轮子“肯定让你不爽.当然我们把类库放到一边,聚焦于 JavaScript的语法,对你最有价值的东西是在你编写 JavaScript你要明确你使用的是那种”编程模式“. 下面主要介绍几个jav…
