This loose form of Singleton cannot be instantiated. All of the members are now accessible through the Singleton variable, accessible through dot notation.   var myCart = {       self: this ,        totalCost: 0,        totalQty: 0,        cart: {},        getCart: function (){ },        updateCart: function (){ }    };    alert( "Total cost: ...
