Klaus Komenda takes us through the history of development patterns of JavaScript demonstrating the pros and cons. Taking a typical JavaScript feature he starts with the old-school global functions method and iterates through a Singleton, Module Pattern, Revealing Module Pattern, Custom Objects and Lazy Function Definitions bringing the same feature up-to-date.
Christian Heilmann offers another incremental improvement to the Module Pattern, and calls it the Revealing Module Pattern. This defines an anonymous object that contains a list of methods and properties that are publicly available. Christian notes that this method also allows you to set up a public property that's privately generated by a method. Christian's improvement makes it quickly clear which properties and methods are public.
