Word origin

The term 'singleton' originated from the concept of a singleton set in mathematics, which is a set with exactly one element. In software development, the singleton design pattern was first introduced by the 'Gang of Four' in their book 'Design Patterns: Elements of Reusable Object-Oriented Software'. The pattern has since become a fundamental concept in object-oriented programming.
