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 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…

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…
