I disagree.  Eloquence is not definitive proof of quality, but it
is one useful sign.

But beyond that, do you have a substantive critique of the book?

I've used it to help teach beginning JS programmers.  I think it's
one of the better ones around.  I don't remember seeing any reviews
of it here, but I have not been paying very much attention for the
last year.

Have you read it?  At least some versions of it are freely available
on the web.

3. Look for earlier definitions in the book for the missing parts.

Christoph M. Becker's response has already done that for the OP.  Such
a response is more informative and IMHO better for the group than a 
snide disparagement of the book in question.
