I'm baffled that this little issue has never cropped up for me until now, but I recently discovered a little annoyance in ServiceNow while iterating through an array. This issue had me going round in circles for hours, so hopefully by sharing my findings with our readers, I can spare some folks the frustration I felt.

First, I'll tell you a little story about how it happened to me, and then I'll tell you the explanation for this odd behavior.
