Please learn to quote.  Signatures are not to be quoted unless explicitly 
referred to.  You did not referred to mine, but quoted it regardless.

You are mistaken, the record shows.  Which is better, *potentially* 
*temporarily* confused people who are given the possibility to expand on 
their half knowledge, or *all-time* mislead people who don't really know 
what they are doing, causing harm to themselves and others through their 
incompetence?

Utter nonsense, or, as Gregor would probably put it: Bullshit!

The `==' operator is supported since the very beginning (JavaScript 1.0); 
the `===' operator was introduced later.  It is only there are circumstances 
where backwards compatibility does not matter that much that it is less 
error-prone to use the `===' operator.  Learn to read.

Your posting and e-mail are perfect examples of why it is a waste of time to 
read postings injected through Google Groups, which I am therefore usually 
do not do.  Most of the people there do not have the faintest idea what they 
are doing including where they are posting to.
