I am in the process of making my own namespace in JavaScript...

(function(window){
    (function(){
        var myNamespace = {
            somePublicMethod: function(){
            },
            anotherPublicMethod: function(){
            }
        }

        return (window.myNamespace = window.my = myNamespace)
    }());
})(window);

I'm new to these kinds of advanced JavaScript techniques and i'm trying to figure out the best way to call public methods from within my namespace. It appears that within my public methods this is being set to myNamespace.

Should I call public methods like...

AnotherPublicMethod: function(){
   this.somePublicMethod()
}

or...

AnotherPublicMethod: function(){
   my.somePublicMethod();
}

is there any difference?
