Consider following code snippet:

function Container(param) {
    this.member = param;
    var secret = 3;
    var that = this;
}

How many private members are in the Class?

Explanation

This constructor makes three private instance variables: param, secret, and that. They are attached to the object, but they are not accessible to the outside, nor are they accessible to the object's own public methods. They are accessible to private methods. Private methods are inner functions of the constructor.
