Thank you, Jarrod, for taking the time to write a comment. As I mentioned in my previous response, I will be writing another post to demonstrate how we can implement this pattern using channels and other Go-specific features. In the world of technology, there are numerous approaches to implementing solutions, and it is invaluable to have individuals like you who read the post and provide constructive feedback. Learning is an infinite ocean, and we are constantly expanding our knowledge.
Also, this port was not about singleton; I have never written about S singleton. You may have confused it with another post.
Peace
