The reason this is mentioned (and things like the part about caching array length in your for loop) is that this tutorial was mostly written back in 2006, when things were obviously a bit different with JavaScript.

The article has gotten updates since then (check the history), but not many and not to the extent it probably needs. Not sure why it keeps getting linked.

Since you seem to have an understanding of what is wrong with it, care to tell about everything you know that should be updated?

I would find that helpful. Since the article is a wiki, I would be willing to edit in any suggestions that magicalist makes, if magicalist doesn’t want to bother doing the editing him or herself.
