  function isEvenNumber(num) {
    if(Math.random() > 0.5) {
      return true
    }
    return false
  }

Took a while, but worked in the end. Be careful with the arbitrary code execution because I'm sure people can do more than generate random numbers!

It's running in the browser. (I checked with an "alert") so its not that bad.

Edit: nvm, it seems (according to a comment here by the author) that it is sent to the server and verified.

Edit 2: indeed, once the answer worked locally, it got sent - and got stuck at "Submitting..." (locally, I clicked the alert)

Too circuitous, too procedural. Just,

  return (Math.random() > 0.5);

You don't need the parentheses either.

or, as Randall Munroe put it,

where 'panic sort' remains my favorite

seems apropros as well
