Re: Re: IE and arrays

I know that would definitely work... however that's not the point I was trying to make.
The construct I was trying to use might be useful in some specific situations... besides most (if not all) Dynamic Languages allow you to do such thing.
That's why I originally coded it that way when developing using Firefox as my testing browser, however IE does not allow it. So, I was wondering is this was another "feature" of IE, or it is the language itself that does not allow a construct like this?

The language itself has different features between its versions, take
a look on the last version proposed by the author and you'll see weird
constructors inherited from languages like Ruby or Python. Besides the
fact that IE supports "JScript" while other browsers support
"JavaScript", each browser support a different engine of it, currently
IE doesn't support these new set of features of the language, so don't
try to use them if you plan to keep compatibility.

well, as you know, IE and FF in fact implement different versions of
what is called ECMAScript (JScript and JavaScript). So, probably
you're right in both cases, it's a 'feature' and it's a language
(JScript) itself. I guess you gotta read language specs to find out more.
goodluck
