A type of ProgrammingLanguage. FunctionalLanguages make the distinction that everything (or near everything) is a function. They often lend to recursion more than iteration. Some examples of FunctionalLanguages are: 

  

 * [Haskell] 

 * [ML] 

 * [LISP] 

  

 Programmers generally choose to code in ImperativeLanguages as they find these easier to make practical applications. It has been theorised that this is because most people learn languages such as C++, BASIC, Java, etc. first and only learn FunctionalLanguages later, never really learning to think like a functional programmer. Perhaps if more programmers were taught to think in a functional style from their infancy we would see more applications written in FunctionalLanguages. Then again, maybe it is just easier to write a useful program in [Python].
