Here's an example of how I use CFIF to alternate row colors. In practice, I
use this with CFOUTPUT, but here I've used CFLOOP so the example is
stand-alone.
----------------------------------------------------------
<CFSET bgcolor = "FFFFFF">
<TABLE CELLPADDING="5" CELLSPACING="0" BORDER="0" WIDTH="600">
<CFOUTPUT>
<CFLOOP INDEX="line_num" FROM="1" TO="10">
<CFIF bgcolor IS "FFFFFF">
<CFSET bgcolor = "E6E6E6">
<CFELSE>
<CFSET bgcolor = "FFFFFF">
</CFIF>
<TR>
<TD BGCOLOR="#bgcolor#">#line_num#</TD>
</TR>
</CFLOOP>
</CFOUTPUT>
</TABLE>

My understand, based on what an expert (seminar instructor) said was that
yes, IIF is significantly slower than using CFIF and should be avoided if
possible. But there are cases where IIF can be used where CFIF can't. For
example, one way of alternating the highlight background color on table rows
uses IIF within the TD tag to pick the background color... something where
CFIF can't be used.

Subject: IIF vs if,else
Ok, after a bit of testing... can anyone tell me what the advantage of IIF
over if (<cfif> or if () {}), else (<cfelse> or else {}).
I tested a simple block of code using IIF and <cfif><cfelse></cfif> & IIF
ran twice as slow...
I can't see any major advantage by using it... yeah, it is kinda similar to
i = (true?1 : 2); in javascript but it's really slow case of the implicit
evaluate() on each part. Would be better if it was implicit & made explicit,
IF NEEDED.
Can anyone give me a decent reason why IIF is better that <cfif>?
