Let me tell you a story about the most powerful pattern in all of programming - and I’m going to tell it the way stories are MEANT to be told. The One-Line Logline “Ensure only one instance of a class exists, no matter how many times someone tries to create it.” Think of it as the “highlander pattern” - there can be only one!
