Aside from the last piece of advice: to have fun. This is a terrible list. Global vars are bad for application level logic and clutter your global namespace. Switch statements are great but only if you have more than 3-4 conditions. Set timeout is a neat trick but it can quickly get you into state based problems. Careful with this one. Buried within are some good nuggets of info, but overall it doesn't get deep enough into the techniques described to show anything like good practices.
I think this was supposed to be satire
This list sounds like a page taken out of one of Douglas Crockford’s talks — of everything not to do.
This is great! At first glance I didn't catch the sarcasm, had to reread the first paragraph.
