We have a lot of logic that processes data and it extensively uses
structKeyExists to determine whether or not data exists prior to performing additional logic. I've been modernizing my legacy ColdFusion code and am wondering if we should invest any time to converting
keyExists(). Are there any benefits apart from readability? Any assumptions regarding which is more performant?
While I've read that looping over a function multiple times isn't the best way to compare performance, it often reveals issues... especially when one performs 2-4 times faster than the other.
Here's some quick stats comparing 2,000 built-in cfml function calls. (NOTE: It didn't matter which version of ACF2016+ or Lucee is used.)
Am I going about this wrong? Am I asking the right questions? Is there any expectation that the performance times would be better (or at least the same) when using
