AndroidToday, I've oddly found IncrementValue in Coldfusion. In my previous time, when I need to increase count in Coldfusion, I always use as follow.
1<cfset mycount = mycount + 1>
2
3<!--- CFScript version --->
4<cfscript>
5 mycount++;
6</cfscript>
2
3<!--- CFScript version --->
4<cfscript>
5 mycount++;
6</cfscript>
Now I don't need to use above native coding and should use IncrementValue instead. Usage is kinda simple.
1<cfset mycount = 0>
2<cfset mycount = IncrementValue(mycount)>
2<cfset mycount = IncrementValue(mycount)>
As Adobe documentation, The integer part of number, incremented by one. It's so sad that we cannot use like step attribute in CFLoop in this built-in function.

<cfset mycount = 0>
<cfset mycount++>

i.e. mycount += 2 is shorter than mycount = mycount + 2
And of course works in both tags and script.

My guess is that incrementValue isn't slow anymore (assuming that the issue was fixed), but why bother using it? var++ is used in other languages (ie. javascript) so if you bring on other developers new to CF, they'll likely just "get it". Plus it's shorter to type.

I think Adobe has fixed the bad performance of IncrementValue just like UUID in CF9. Honestly, I've not tested yet the comparison of IncrementValue and others function just like cfset count++.

Can you let me know why you prefer <cfset myvar++>? Because of performance?

Thanks for letting me know the usage of "step". That's one is very new to me.

That's what I know either.

I haven't done any performance testing. It's just a personal syntax preference. IncrementValue(myvalue) just seems a lot more clunky to me than myvalue++
