For those that are familiar with object-oriented languages, modules are JavaScript “classes”. A builder pattern is a design pattern that lets us extract the object construction out of its own class (its representation) so that it can be used for multiple different representations. The builder pattern is a creational design pattern used to create objects. Today we are going to talk about a creational pattern that in many situations can represent a useful alternative to… | Web design web development news, website design and online marketing.

The next time you develop web applications, think about developing modules that are loosely-coupled with each other and adopt the Observer pattern as a means of communication. The base class contains the business logic. For some reason it's being left behind in any design pattern usage in JavaScript. The JavaScript code has a Shop (the Director) and two builder objects: CarBuilder and TruckBuilder.
