@EionRobb - I hadn't even thought about strict mode yet. Good catch!
@mgd020 - Shits and giggles lol. This actually came up because of production code so somebody did it in production.
@gkaykck - Haha. Well done ;). I absolutely don't expect people to know this stuff by heart. That's why it's such a weird challenge. This isn't stuff that you should know because you should never be doing this nonsense to begin with.
