This is not the case with functional- there is a very rigorous definition of what is meant by “functional”, and I'd like to introduce people to it. A while back, I blogged about (Mis)using C# 4.0 Dynamic – Type-Free Lambda Calculus, Church Numerals, and more which was a fun post and got some good feedback and solid reading numbers. It is true that there are lots of people who are not very familiar with (true) functional languages, lambda calculus, or combinatory logic, and who have the vague notion that Lisp is a functional language because of its functional appearance or . Unfortunately, most people outside of programming and computer science don't know exactly what computation means. This is an improvement, especially the intro. Don't worry about lambda calculus, type theory, category theory, monads, morphisms, or any such abstract concerns. Running commentary tries to point out common idioms, and provides links to ClojureDocs documentation for newly introduced functions. I believe that learning to program in the functional Marginalia literate programming tool. First, one thing that many functional languages do is to write their specifications explicitly in terms of a translation to the lambda calculus to specify the behavior of a program written in the language (this is known as “denotational semantics”). This is exactly like the Lambda Calculus: names are variables, text blocks are expressions, and headlines are function heads, only instead of being printed in bold, they are surrounded by a λ and a dot, so we know where they begin and end. Many may have heard of Turing Machines, but these . The first part is long I had taken courses Scheme and the lambda calculus in college, and I thought I had a pretty good understanding of functional programming. Newbies might get the impression – as I did – that Emacs was all about functional programming because all I knew back then was C, SQL, and some weird proprietary stuff at work. So, let's continue our journey of brain-exploding theoretical foundational In fundamentalist functional programming the above is the most useless type for a function: it takes nothing and produces nothing, hence all those guys can be compiled away, right? I've split the introduction to this post into two parts. And thus tend to shade into buzzwords at the edges. I've heard newcomers to Clojure ask how to get started with functional programming.
