Indeed! That is much nicer looking code.

I don't work with JavaScript, but in some of the examples I have seen I
have really like how you can do your regular expression pattern declaration
inline. I can only guess that VBScript cannot do this because regular
expressions are not native to the language. I really wish they had at least
taken this opportunity and used the extra time to fully implement them.
There are many aspects of regular expressions that I have never used, but I
have had a few instances in the past where I was quite annoyed that they
could not perform 'lookbehind' matching.
