Singleton School

Singleton School - The singleton pattern is a fully paid up member of the gof's patterns book, but it lately seems rather orphaned by the developer world. From the dagger 2 documentation i noticed that you can have a @singleton annotated class. A singleton is special because its instance is created only once, and a metaclass is the way you customize the creation of a class, allowing it to behave differently than a normal. What is the simplest/cleanest way to implement the singleton pattern in javascript? } i understand how this is thread safe from other questions here on so, but what i don't understand is how. Static singleton& instance() { static singleton s; Private singleton() {} public static singleton instance {. I know it has to do with the fact making a class singleton is like making that unique instance a global variable, but it's also doing a lot more. When should i use the singleton? What is the purpose of marking a class as @singleton as i have tried to do.
