<summary>
Finally, after all those years, I got around to reading "<nop>JavaScript: The Good Parts" - pretty
much from cover to cover.
</summary>

All in all, a great book! However, it left me even more confused about
how <nop>JavaScript sets "<tt>this</tt>" than I was before. Fortunately, I found the discussion at http://stackoverflow.com/questions/3127429/javascript-this-keyword and the article at
http://www.digital-web.com/articles/scope_in_javascript/ which both clarified 
open questions for me. But I am pretty sure I will forget <nop>JavaScript's context subtleties 
fairly quickly, and then I will have to look them up again. Oh well. <!-- Maybe I should
also watch Doug Crockford's presentation at http://www.youtube.com/watch?v=hQVTIJBZook ... -->

Crockford's approach is to focus on a subset of <nop>JavaScript which he considers sane,
Of course there is much debate on what belongs into the subset and what doesn't.
For example, Crockford bans the <tt>++</tt> and <tt>--</tt> operators because they remind
him too much of obfuscated C++ code. I did not find this particular advice too convincing, and it
seems [[http://stackoverflow.com/questions/971312/why-avoid-increment-and-decrement-operators-in-javascript][I am not alone]].

To experiment with code from the book and test some code of my own, I used the [[http://trac.webkit.org/wiki/JSC][jsc]]
command-line JS interpreter on the Mac, and also toyed with http://jsfiddle.net/.
(On Ubuntu, I guess I could have used [[http://manpages.ubuntu.com/manpages/hardy/man1/rhino.1.html][rhino]].)
