Question

Currently I have this structure:

(function(myScope) {
  myScope.public = function() {alert(\"I\'m public!\")};
  myScope.privileged = function() {alert(\"I can c

You will need to break your code down into smaller parts. For each thing, you might want to make the instance reference local-scoped, but you can import the class/code/functionality from a different file.

Blowing up your example to three files:

function makeAlerter(state) {
  return function() {
    alert("I'm "+state);
  };
}

(function(myScope) {
  var private = makeAlerter("private"); // not the whole private coding here
  myScope.privileged = function() { // but the privileged code needs to stay
    alert("I can call private!"); private();
  };
})(window.myObj);

(function(myScope) {
  myScope.public = function() {alert("I'm public!")};
})(window.myObj);
