The slideshow is a bunch of JS introduction, and barely any "metaprogramming". If you are really looking for a good JS read, check out this article:

Thanks. That was a good link. I have bookmarked it.

It's much more explanatory, though. I believe the intent of the main linked article is a presentation giving more of a tour to what is possible. The author makes clear at the end that the reader might not get it all -- it's just an overview.

I didn't find much difference in terms of metaprogramming, however. Were there any concepts in your article that weren't mentioned in the first one? I might have missed it.

I'd use the presentation as a way of glossing over the high points, and then refer somebody to your link as a way of figuring out how it all works.

There aren't new concepts, just actual explanations of what the presentation is talking about.

"I'd use the presentation as a way of glossing over the high points, and then refer somebody to your link as a way of figuring out how it all works."

Probably a good strategy.

"Nearly everything is a hash... everything else is an Object"

Huh? Objects are basically hash tables/associative arrays in JavaScript...

This is a great presentation including small samples of Javascript showing off all the cool parts. (I'm adding this comment to catch folks that might have missed the article post but are reading the new comments page) It's a cool resource for folks wanting to do a quick check of their JavaScript programming chops.
