title: Processing.JS Error - TypeError: e is undefined
body: <p>I'm having this strange error on <a href="https://www.khanacademy.org/cs/dev-khan-logins-2014/5845868966576128" rel="nofollow" title="Here">here</a>, which I figured out the Login.prototype.* is causing the issue, and I can't find a workaround. Here is the errors Firefox printed into the development console.</p>
  
  <p>TypeError: mutating the [[Prototype]] of an object will cause your code to run very slowly; instead create the object with the correct initial [[Prototype]] value using Object.create jshint.js:8417</p>
  
  <p>TypeError: e is undefined</p>
