JavaScript Design Patterns: Singleton

This is the first in what should be a pretty long series about JavaScript design patterns. In 1995, Erich Game, Richard Helm, Ralph Johnson and John Vlissides (known as the Gang of Four) published Design Patterns: Elements of Reusable Object-Oriented Software, a book cataloging recurring solutions to common dilemmas in software architecture and design. It also started a common vocabulary for referring to these solutions. If you’d like to know more you can find it on Wikipedia.
