var myNamespace = myNamespace || {};

myNamespace.MyConstructor = function(opts) { this.options = opts; };

(function () {
    
    function myPrivateMethod(t) {
      console.log("myPrivateMethod" + t.options.a);
    }

    myNamespace.MyConstructor.prototype = {
      options: {},
      
        myPublicMethod: function () {
            myPrivateMethod(this);
        }
    };

})();


var o = new myNamespace.MyConstructor({a: 1});
o.myPublicMethod();

var o2 = new myNamespace.MyConstructor({a: "la quinta"});
o2.myPublicMethod();

Yes, thanks for catching that.

The weakness of this approach is that the constructor cannot set private fields.
