Experience in CFML would be handy. You don't technically need any previous experience in any language although general experience in programming helps you with the concept. Do you at least know / understand the concept of HTML?
The difference between most programming/developing languages is syntax. Most languages are based upon C; but this should not be considered a reason to learn C.
If you learn one language, then you also learn the logic. The logic is 99% the same across all languages. This makes it easier to learn the syntax of other languages.
So, to answer your question, there is no specific language that will help you with CF other than CFML. But, as haxtbh pointed out, a solid grasp of HTML is very beneficial.
Thank you!!) Unfortunately no, I am a beginner, but I want to make first step in learning how to create web-apps. Just need to understand from where to begin.
Learn CF in a Week is a good place to start for Coldfusion.
Thank you very much!!
