My code:

function bouncer(arr) {
  return arr.filter(isTruthy);
}

function isTruthy(a) {
  arr = [false, null, 0, "", undefined, NaN];
  for (i = 0; i < arr.length; i++) {
    if (arr[i] === a) return false;
  }
  return true;
}

bouncer([false, null, 0, NaN, undefined, ""]);

@yielder thanks for posting this issue!
The problem is that NaN === NaN returns false. To check if the value is NaN use isNaN.
If you have problems with your code, please, post a message in our Gitter chat room first, thanks.
