Singleton Pattern

The Singleton Pattern is a design approach used in programming to ensure that a particular class has only one instance throughout the application. Think of it like a shared resource, such as a single database connection or a configuration manager, that all parts of the program access. This pattern controls the creation process so that only one object is ever created, promoting efficiency and consistency. It provides a global point of access to that instance, making it straightforward to coordinate actions across different parts of the program that rely on the same resource.
