var Example = window.Example || (function() {
    var self = {};
 
    // This method:
    self.Update = function() {
        var self = {};
 
        self.itemcurrency = function() {
 
        }
 
        self.currency = function() {
 
        }
 
        return self;    
    },
 
    // Or this method:
    self.Update2 = {
        ItemCurrency: function() {
 
        },
 
        Currency: function() {
 
        }
    }
 
    return self;
})();
