I don't want to start a fight here... (have you ever noticed that when =
someone says that, a fight occurs?)

Technically, 0 is not a boolean value, it's an integer.  True and False =
are the only determinate boolean values.  The JavaScript standard does =
allow non-boolean values to be coerced into boolean values (that is, =
JavaScript is supposed to turn 0 into false and everything else to =
true), but that's just because it only has one kind of scalar value.  =
Java, for example, doesn't allow it.

So, while it is wrong for MSIE 5 to fail the coercion mandate, it's not =
because 0 and 1 are boolean values.  It's because MS undoubtedly wrote =
its JavaScript engine in a strongly typed language, and they didn't =
think that anyone would use 0 and 1 as boolean values.  (Which *ahem* =
they shouldn't.)

Still not an excuse, of course!  :)

I have to say that I'm fond of strongly typed languages for object =
oriented development (which is redundant, really), but for scripting =
languages meant for use by non-to-amateur-programmers like JavaScript, I =
have to say it's unreasonable to expect strong typing.

JavaScript fully implements Boolean values. Win IE5 apparently only =
supports
true/false.

Here's a working example on my site:

When I tried changing "return false" to" return 0" it broke the script.
