the perfect javascript tutorial or book?
 

I'm looking for javascript tutorials or books that meets the following criteria:

1. Very thorough: Starts with the most fundamental concepts and progresses logically from basic to advanced concepts, without skipping over important ideas for the sake of expediency.

2. Lots of small practice exercises that parallel the concepts and syntax being learned.

I've looked at a lot of tutorials, but they all tend to be lacking in one of these areas or the other.

Unfortunately I don't have a corresponding recommendation for you but I'd like to say something to the topic nevertheless. In practice the most important difficulty in developing functionalities in javascript is how to test it on the available platforms as there are so many. Thus most programmers use ready-to-go libraries to write shorter code that works on a lot of platforms. So if you go to one of the following addresses and look at the docs you might be better off...
