Yes, it isn't, for there is not "*the* JQuery file".

Usually jQuery is used in a custom minimized package along with so-called 
jQuery "plugins" (e. g. [1]).  Not only do the jQuery versions in such a 
package differ from another, the sets of minimized "plugins" and versions 
thereof differ as well.

This is not a jQuery-only issue.  Script authors need to be aware that fewer 
HTTP requests for faster loading come at the price of reduced cacheability.

There is no "Javascript" [2], and if you write your scripts with 
compatibility in mind (i. e., you consider the APIs available at the time 
and use runtime feature tests to detect them before you use them), you will 
probably not have any compatibility problems with a new browser as vendors 
are very intent on keeping their new browser versions backwards-compatible.  
However, you may want to augment your tree of feature tests with another 
branch for a new API that the new browser version has to offer (giving it 
precedence if it offers a significant advantage over the other branches, 
such as standards compliance), and you may want to cut old branches.  BTDT.

The few checks for "old browsers" that jQuery hides, if any (see Resig's 
ridiculous compatibility matrix that he calls "cross-browser"), have to be 
implemented as much as backwards-compatibility is required for one's use-
case (and not as John Resig claims to know it is), and can be implemented in 
a more efficient way then.

Yes.

"They" do.  A few more bad books are on the market already, and "they" do 
not hide that fact (see jquery.com at the bottom).  It is "docware" (an 
interesting term I have read on Usenet recently).

> why would they need to hype it with overblown claims?

It is a cult of ignorance.  Cult leaders want attention and dependence from 
their followers; the illusion of power and control to the disadvantage of 
many.  As with most successful cults, it is so clever a scheme that most 
people are not able or willing to recognize it – until it is too late.  
Insofar the concept does work for some time.

No, but judging from the overall code quality and reasoning for it coming 
from their authors, the majority of third-party libraries published on the 
Web was written by wannabes, jQuery included.

If it *rolls*, by comparison, and if you can know *why* that is, then you 
better do that.  Once.

We have been over this here ad nauseam.  Please research before you post.
