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.

files-importer is a Node.js command line tool, written in functional programming style, which synchronously copy the contents of a directory (include subdirectories recursively) to another location without creating duplicate files. It can be used to import only images and videos that have not already been imported from a camera or a memory card.
