If I have a parent and a child window, and if I create an array in the
child window, and pass it as a parameter to the parent window, it's
still an array, and its methods still work (like the 'forEach').
However, if I try to figure out if it's an array by looking at the
constructor property, I get that it's not an array. I got this behavior
in IE6 and Firefox, is this a bug or am I doing something wrong? I
pasted the code below.
Thanks!

Hi,
i am a oo (c#) programmer, and have not used javascript for a while and
i cant work out how javascript manages its references. Object
References work for simple stuff, but once i have an object collection

Clearly there is something about javascript's usage of passing "By ref"
that i am not getting. i have had a look on the web and found some

HI,
One more small doubt from today's mail.
I have certain function which returns a pointer (sometimes a const
pointer from a const member function).
And certain member function needs reference (or better a const
reference).
for eg,
const PointRange* points = cc.points(ptAligned);

If I don't specify "ref" in the argument list when passing an array to the
callee, I am passing the array (reference) by value. But this makes me
confused because it actually means a "reference" of a "reference"??As I pass
the array by value, the callee can change that array. However,when I use
ref, the callee and caller point to two different arrays. So could anyone
please explain the 2 different situations?

I have a web page where a member can open up a chat window (child window) with another member.
- From there the member can also navigate to other web pages.
- From other pages in the site, they may also open up new chat windows with other members (just not the same one).
- Each chat page is opened with the member name as the window name.
- When I log off from the web page, I would like all the chat windows to automatically close.
