Functional programming

In computer science, functional programming is a programming paradigm where programs are constructed by applying and composing functions. It is a declarative programming paradigm in which function definitions are trees of expressions that map values to other values, rather than a sequence of imperative statements which update the running state of the program.

The F language can be considered as a reduced version of the Lisp language with some simplifications and modifications. It takes the basic syntax and semantics from Lisp.
