Question

This

<cfif len(x)>

Or

<cfif x NEQ "">

Which one is more efficient and readable? Function call vs comparing empty string?

Answer 1

I use:

 if(len("String"));

I think the code is much cleaner and as they like to say “expressive”. With this syntax what you are saying with the code is “if this string has a length” do this where with the opposite your code is “saying if the length of the string is a blank string do this”.

I also use ColdFusions loose boolean values for lots of things like in addition:

  if(a + b){
   ...
   }
