To compare testA and testB, which are both SubComponents, you could use
the IsEqualTo method.
Point, Vertex, and Edge objects also support IsEqualTo.
Testing Index is comparing integer values. Two vertices on two distinct
objects can have the same index value.

Subject: Re: So why won't this conditional work?
Ok, I follow this as it is pretty much what I was expecting might be the
case. So then the question is what is the most reliable way to
de-reference the components I am trying to match. While I've got years
of experience with Perl, I have absolutely no experience with Jscript.
Would you convert the content of the reference to a string then use
regex, or is there a simpler method. I note that Ian's example using
.Index does work, but would any two elements from two separate objects
with the same index match or is the Index also providing a backtrace to
the object or origination. In other words is the conditional just
testing the integer represented by the index or the actual element? My
thinking is that it is only testing the integer value of the Index,
correct? Therefore any two elements which happen to have the same index
could fool the conditional into providing a true return value.
