Functional Programming / Learn Vimscript the Hard Way
Functional Programming We're going to take a short break now to talk about a style of programming you may have heard of: functional programming. If you've programmed in languages like Python, Ruby or Javascript, or especially Lisp, Scheme, Clojure or Haskell, you're probably familiar with the idea of using functions as variables and using data structures with immutable state. If you've never done
Functional Java
Functional Java is an open source library facilitating functional programming in Java. The library implements numerous basic and advanced programming abstractions that assist composition oriented development. Functional Java also serves as a platform for learning functional programming concepts by introducing these concepts using a familiar language. The library is intended for use in production a

Functional Programming | Clojure for the Brave and True
So far, you’ve focused on becoming familiar with the tools that Clojure provides: immutable data structures, functions, abstractions, and so on. In this chapter, you’ll learn how to think about your programming tasks in a way that makes the best use of those tools. You’ll begin integrating your experience into a new functional programming mindset. The core concepts you’ll learn include: what pure
