There's a fair amount of disingenuity, or perhaps just willful ignorance to the statistics here and I talk to a lot of people who are astonished that CFML is still in use due to the alleged massive numbers of vulnerabilities.  One would think simply touching the code might give you rabies.  Some CFers suggested that it's a form of "virtue signalling" by infosec professionals to throw CF under the bus, winking at each other over there shared distaste for a platform they have little knowledge of but assume sucks.

I was adding a feature to CommandBox CLI this week when I typed up some code that iterated over the keys in a struct, filtering out the ones it needed and then performed an action on the matching ones.  I used the functional methods structFilter() and structEach() in CFML.  They are an example of functional programming as they accept functions as input.  This also means we can call them "higher order" functions.  But termininologo aside, I typed up the same code using an older interactive approach just to compare the too.  It was an interesting and rather self contained example so I thought I'd share it as a real life use case for FP (functional programming).
