Javascript: should my implementations be hidden?

Question

As a C # programmer, I have a bit of a habit of making things private, which can and should be private, and I always get a weird feeling when the JS type provides me with all its personal parts (and this feeling didn't 'cause'). Let's say I have a type that has a method drawthat internally calls drawBackgroundand drawForegroundthat don't make sense to call on its own. How to implement this?

Option 1

Foo = function(){
  this.draw();  
};

Foo.prototype.draw = function(){
  this.drawBackground();
  this.drawForeground();
};

Foo.prototype.drawBackground = function(){};
Foo.prototype.drawForeground = function(){};

Option 2

Foo = (function(){

  var constructor = function(){
    this.draw();
  };

  var drawBackground = function(){};
  var drawForeground = function(){};

  constructor.prototype.draw = function(){
    drawBackground.call(this);
    drawForeground.call(this);
  };

  return constructor;

})();
