Overview of AMD Excerpt From Writing Modular JavaScript With AMD, CommonJs & ES Harmony: When we say an application is modular, we generally mean it’s composed of a set of highly decoupled, distinct pieces of functionality stored in modules. As you probably know, loose coupling facilitates easier maintainability of apps by removing dependencies where possible. When this is implemented efficiently, its quite easy to see how changes to one part of a system may affect another. Unlike some mor
