Clojure - Functional Programming for the JVM by R. Mark Volkmann, Partner Object Computing, Inc. (OCI) last updated on 6/2/13 Contents Introduction The goal of this article is to provide a fairly comprehensive introduction to the Clojure programming language. Please send feedback on errors and ways to improve explanations to, or fork the repository and send a pull-request. You said X, but the correct thing to say is Y. Updates to this article that indicate the "last updated" date and provide a dated list of changes will be provided at Code examples in this article often show the return value of a function call or its output in a line comment (begins with a semicolon) followed by "->" and the result. (+ 1 2) ; showing return value -> 3 (println "Hello") ; return value is nil, showing output -> Hello Functional Programming Functional programming is a style of programming that emphasizes "first-class" functions that are "pure". In practice, applications need to have some side effects.

Clojure Cheatsheets Basic Web Development | Clojure Documentation | Clojure Docs This guide covers building a simple web-application using common Clojure libraries. When you're done working through it, you'll have a little webapp that displays some (x, y) locations from a database, letting you add more locations as well. It's assumed that you're already somewhat familiar with Clojure. If not, see the Getting Started and Introduction guides.

This guide uses Clojure 1.5, as well as current versions of the component libraries noted below. Conceptual Overview of Components We'll use four major components (briefly described below) for our little webapp: RingCompojureHiccupH2 Ring Ring (at clojars) is a foundational Clojure web application library. For this tutorial, we won't actually need to deal with these maps by-hand, as you'll soon see. For more info, see: Compojure Hiccup [:p "Hello, " [:i "doctor"] " Jones."] becomes See Also
