Singleton Pattern

The Singleton Pattern is a creational design pattern that ensures a class has only one instance and provides a global point of access to that instance. This pattern is particularly useful when there's a need to coordinate actions that can't be shared among multiple instances.

The Singleton Pattern with sync.Once is a robust and elegant solution for managing single instances across multiple goroutines. By combining the benefits of the traditional Singleton Pattern with thread-safety, this approach enables secure and efficient access to shared resources and configurations.
