It's really unfortunate to see so many pedantic posts on this thread. The article author explored something that probably isn't obvious to most programmers who didn't come up from low level work. And I am sure this isn't on the radar for your average PHP, JS programmer. And that's fine. No, the code isn't production ready. I didn't get the sense that this was the article's intent. The author actually did a very nice job of explaining one approach. Good article and very accessible . Ease up. Help him make it better without being so condescending.
