Re: Comparisons - Your thoughts
While I'll agree that the readability/maintainability factor is
important from a developer's viewpoint, that particular article was
specifically focused on performance and was merely pointing out which
functions were technically faster.
If one function is built to be faster than another function, then that's
how it's going to perform, regardless of whether or not it's easy for
the developer to read.
That being said, I'll have to agree with Brad and Charlie on sometimes
coding what's easiest to read and maintain. You do reach a point where
maintainability can play a larger role than squeezing out every tiny
little millisecond of speed (on most apps).

I'd be leery of something that says, "always".
Sometimes, it's OK to consider the readability/maintainability factor.

Re: Comparisons - Your thoughts
According to this "Performance tuning for ColdFusion applications" post,
you should always use compare() or compareNoCase() instead of the IS NOT
operator, and you should use listFindNoCase() or listFind() instead of
the IS and OR operators.

I have long been in the habit of using EQ and NEQ (and now moving to == and !=)
for numbers in all cases, since there is no such thing as 'sort of equivalent',
like there is with strings ('foo IS FOO' etc). For strings I use IS, unless
case is important, and then I use CompareNoCase().

RE: Comparisons - Your thoughts
I prefer Seriously though, do what looks best and is easiest to read and maintain. I have seen performance benefits of one way over another, but they are few and far between. Most of my business logic is in cfscript these days and I'm usually kickin it with the ECMA operators like == != etc. ~Brad Original Message Subject: Comparisons - Your thoughts From: Chuck Weidler Date: Wed, July 15, 2009 1:52 pm To: cf-talk I was wondering what the community was doing with comparisons, like in a cfif. I have done it many different ways. List below are just few examples, and yes I know that the Compare() and CompareNoCase() should be used for string comparison and not numbers, but I have seen it done that way in some code that I maintain at work. I'm not saying one way is better than another I just want you to give your opinions. ~| Want to reach the ColdFusion community with something they want?
