It used by be a markup language like:

  <cfif blah="something is true">do this<cfelse>do that</cfif>

  <cfscript>
  // scripty stuff
  </cfscript>

Ahh. Yeah. Well that sparks a memory of why I quickly went another direction after looking at it back then when I was learning web dev lol. Tbf a lot of people were, probably still are, using PHP and JavaScript way back then too. It just made sense for me to do some MVC style separation long before I found out there was an acronym for it.
