Encapsulation In Javascript Module Pattern

I was reading this link http://addyosmani.com/largescalejavascript/#modpattern And saw the following example. var basketModule = (function() { var basket = []; //private return {

Solution 1:

In the first variant you create an object without the possibility to create new instances of it (it is an immediately instantiated function). The second example is a full contructor function, allowing for several instances. The encapsulation is the same in both examples, the basket Array is 'private' in both.

Just for fun: best of both worlds could be:

var basketModule = (function() {
   functionBasket(){
        var basket = []; //privatethis.addItem = function(values) {
            basket.push(values);
        }
        this.getItemCount = function() {
            return basket.length;
        }
        this.getTotal = function(){
            var q = this.getItemCount(),p=0;
            while(q--){
                p+= basket[q].price;
            }
        return p;
       }
     }
   return {
     basket: function(){returnnewBasket;}
   }
}());
//usagevar basket1 = basketModule.basket(), 
    basket2 = basketModule.basket(),
