<script>
  function ConstructorPrivateMethods() {
   function privateMethod1(n) {
    return 2 * n;

   function privateMethod2(n) {
    return 3 * n;
   }
  
   this.publicMethod1 = function(n) {
    return privateMethod1(privateMethod2(n));
   };
  }
  
  function PrototypePrivateMethods() {}
  
  (function() {
  
   function privateMethod1(n) {
    return 2 * n;
   }
  
   function privateMethod2(n) {
    return 3 * n;
   }
  
   PrototypePrivateMethods.prototype = {
