Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
I agree. This is not a best practice. The instance should be protected from direct modification by declaring it as a variable inside a closure.
Since isn't really a closure, there is public access to change Singleton.__instance. Is this really best practice?
Elegant.
Singleton is a javascript object. so, with
Singleton.__instance = this;
we are creating a property __instance on the Singleton object and setting its value to this.
The if condition checks if the Singleton object has __instance property on it and returns that if its present, so, basically using the same "this" object everytime.
What I don't get is calling 'Singleton' from within 'Singleton'. Obviously this is allowed so we have some kind of closure and that's why __instance keeps the instance value like a ststic.
I think i understand the logic of what's going on here, but how does the .__instance work? I can't seem to find any documentation on it.
