For those visually oriented people who might learn best by using
images there are some sources which I have found very fascinating:

1) netbeans 6.7.1 'Navigator' shows a compact summary of a page or js
code like this http://www.24.fi/optimistx/clj/images/fork.png

2) Herong Yang shows constructors, objects, prototypes using images,
which is easy to memorize
https://www.herongyang.com/JavaScript/Inheritance-Prototype-Object-...

3) David Flanagans book, 5th edition from the year 2006, is partly
readable in the net also, http://books.google.com and keywords David
Flanagan. Not many pictures :(, but examples easy to understand).
Almost 1000 pages...
