I ran into a blog entry today by David B. Calhoun on “How to spot outdated Javascript”. I found it to be such a great resource that I had to put it here so I can always reference it.

There’s a gazillion references out there on how to do things in JavaScript, but hardly all of them are correct. So how do you know what not to do?

This blog entry not only tells you what not to do but why not to do it.
