Even though my book was designed to focus on Closure rather than JavaScript in general,
there were a number of pain
points in the language that I did not think were covered well in other popular JavaScript books,
such as </em><a href="http://www.amazon.com/gp/product/0596517742/ref=as_li_tf_tl?ie=UTF8&camp=1789&creative=9325&creativeASIN=0596517742&linkCode=as2&tag=bolinfestcom-20">JavaScript: The Good Parts</a><em> or

So that the book did not lose its focus, I relegated this and my essay, 
<a href="%(host)s/javascript/inheritance.php">"Inheritance Patterns in JavaScript,"</a>
to the back of the book among the appendices.
However, many people have told me anecdotally that Appendix B
was the most valuable part of the book for them, so it seemed like this was worth sharing
more broadly in hopes that it helps demystify a language that I have enjoyed so much.
