// NOT AN APPLICATION, I JUST WANTED TO TAKE YOUR TEST. =)

// 1: how could you rewrite the following to make it shorter?
if (foo) {
  bar.doSomething(el);
} else {
  bar.doSomethingElse(el);
}

// ANSWER

// Class.extend takes a function that returns the options object
//     it is passed the accessor function generated in the Pvt.js example above
var Person = Class.extend(function(pvt) {

  // private static member
  var species = "Homo sapien";
  
  return {
    init: function(isDancing) {
      // pvt(this).invisible === undefined

CrabDude

// Utilize a closure to keep the private members private
var Person = (function() {

  // Generate a private instance member accessor function "pvt"
  var pvt = Pvt(),

    // private static member
    species = "Homo sapien";
  
  var Self = function(isDancing) {
