Singleton Pattern

The video tutorial introduces the Singleton pattern, a design pattern that ensures only one instance of an object is created. It explains the pattern's relation to the module pattern and its use cases, such as managing a single user session. Despite its utility, the Singleton pattern is often criticized for providing a global point of access, which can hinder encapsulation and debugging. The tutorial includes a JavaScript implementation example, demonstrating how to create and test a Singleton instance. The video concludes with a brief mention of the upcoming topic, the factory pattern.
