accessing methods in JavaScript object

Question

Consider the following Java script code:

    var myObj = function (  ) {
        var x = 0;
        return {
            addup: function (y) {
                x += y;
            },
            getX: function (  ) {
                return x;
            }
        }
    }();

This function returns an object with two methods (if I am not wrong).

now, two questions:

how can I call the two methods returned from the function?
can those methods still have access to the variable x ?

thanks,

myObj.getX(); and myObj.addup(5);
Yes, they still have access

how can I call the two methods returned from the function?

myObj.addup(10);
var xValue = myObj.getX();

can those methods still have access to the variable x ? Yes

addup doesn't return anything.

You've created "template" object myObj with private x propery and two public methods.

To create object based on your "template" call var obj = myObj();

You can call them like obj.addup(2); and obj.getX();
Yes those methods have access to Private x variable from them
