We are talking about self-declared eloquence, which should make you 
suspicious.

The fact that the OP as a beginner should be subjected to code that does not  
show which used functions are JS-native, and which are to be found elsewhere 
in the book, does not give me much confidence.

It is clear the book is needlessly complex for the OP.

I have never heard of a JS-book that was not:
outdated, incomplete, full of errors, error-prone, overselfconfident, etc.

JS should better [imho, but that is always implied] be learned than taught. 
learned by specs, example, trial and error, where the 'teacher' is absent of 
does not want to express superior knowledge.

If found that is true for most other subjects too, believing in a revered 
teacher usually sets you of on the wrong foot.

One really should not have to do that, such definitions should be 
backpointed.

Now you are talking, rubish I mean, as 

1 why should a responce be "good for the group"?

2 why should a responce be informative?

3 why should a response be be compared with an 'already' one, also given the 
nonsequential nature of the usenet server system?

4 what is wrong with a 'snide disparagement'?

All that is required according to netiquette and charter, is 'on topic', 
meaning 1 about JS in general or 2 about the NG.
