Presentation is not so professional
The author needs to use some professional looking slides.
She is explaining using a text editor (and the html page for the scripts) during the entire training session. It's like a college lecture half century ago. If you are lecturing Latin grammar using this method this may be OK (but I'm sure that even many modern Latin teachers will use nice PowerPoint slides). It's irony that she uses an outdated teaching method in teaching modern technology. I was going to give only 1 star, but if you stick to (or should I say, endure) her lecture, at least she makes sense. If she adds well-organized presentation slides in her future version, the rate could be four or five stars (depending on the quality of the slides). $20-$30 would have been the right price. For $100, I don't think that it's worth. I think that a well-written book is much better. Not recommended for 2007 version.
Great introduction to javascript
If you're new to programming and javascript, this is a great resource for getting you started. The video keeps the concepts and examples simple without dumming anything down, which is extreemly helpful. I found the personal insights by Dori especially enlightening. They provided good context for how javascript fits into the web development world.
