The original issue became evident particularly when the feature test statement seeking out whether the addEventListener() method exists was interpreted by Firefox v27 -- this, actually, constitutes the first issue. Then, the second issue becomes apparent in the event that I do decide to keep the feature test declaration in the document. Consequently, I am forced to change the placement of the [].forEach() method.
What transpired [tonight] instead was that my favorite, preferred "zorrito" browser of choice suffered hiccups in version 27 when it did not use to be the case in version 17 before the end of 2013 when I had originally constructed something similar to the exercise painted above. I happened on this "pulga" totally by accident as I was going to brush-up on my ES5 array method skills and I was barely beginning to organize previous works with the purpose of building on those previous lessons and exercises when things got "entertaining." Your competitor’s browsers for the moment all resist making any distinction and will render any which way in either case.
Finally, I must say that this is similar to one of [George Carlin’s] life's little moments because as another friend of mine would say "if you or anybody in this business cannot laugh at yourselves, then, who can you laugh at," right? If it’s not any trouble you can put me on your Christmas list this year so that I can find my sparkly, new and burnished FirefoxOS phone in the mail come around next winter… I’m just sayin’ is all ;) You’re never too old to dream by the way! peace.
You can locate Group 1, Group 2, and Group 3 in the code and (un)comment accordingly. Thank you in advance. And, say "hi" to Mr. Eich, too =)
