I just read a few threads on the discussion of singleton design in javascript. I'm 100% new to the Design Pattern stuff but as I see since a Singleton by definition won't have the need to be instantiated, conceptually if it's not to be instantiated, in my opinion it doesn't have to be treated like conventional objects which are created from a blueprint(classes). So my wonder is why not just think of a singleton just as something statically available that is wrapped in some sort of scope and that should be all.

From the threads I saw, most of them make a singleton though traditional javascript

new function(){}

followed by making a pseudo constructor.

Well I just think an object literal is enough enough:

var singleton = {
   dothis: function(){},
   dothat: function(){}
}

right? Or anybody got better insights?

[update] : Again my point is why don't people just use a simpler way to make singletons in javascript as I showed in the second snippet, if there's an absolute reason please tell me. I'm usually afraid of this kind of situation that I simplify things to much :D
