A Surprisingly Clear Slide Presentation on Unobtrusive JavaScript and jQuery

One of the many RSS feeds I consume is the one from Ajaxian, and there's a good read at least once a week there. Today there's a post on and embed of a presentation about Unobtrusive JavaScript and jQuery.

I point this presentation out for a couple of reasons:

1. The presentation is clear, and makes sense without the speaker audio. That's very rare, especially for a presentation on code.
2. I didn't really "get" the idea of unobtrusive JavaScript. Now I do. Those first 20 slides are great.
3. It provides a surprisingly good introduction to jQuery in very little text. Code examples are well thought-out and can be followed easily.

I recently finished a project where I used jQuery as the primary JavaScript library. I learned a lot from using it, and I'll be posting soon about some "issues" I had with the library. It's a good, but wildly uneven, library.
