Functional programming is the future of software development. As software gets ever more complex, unintended side effects flourish - you push on one side, and something unexpected squirts out the other. Functional programming cuts down on complexity through high-level abstractions, and avoids unintended side effects through pure functions. The result is simple and elegant code that captures the essence of the problem you're trying to solve. Fortunately, functional programming is easy to learn, and this tutorial will get you started.

To follow along with the tutorial, we recommend that you download the Racket software:

If you use your OS's package manager to install Racket, make sure you install its IDE, DrRacket

Target Audience: Developers, architects
Prerequisites: Basic programming knowledge
Level: Basic

Extended Abstract:
Functional programming is the logical continuation of object-oriented programming: OOP managed to encapsulate mutable state with the goal of ultimately eliminating it one day, and functional programming finally realizes that vision. Language implementations have been mature and robust for many years now, and the practical functional languages - Haskell, OCaml, Scala, Clojure, F#, Racket, Erlang, Elixir, Swift - all have thriving communities and ecosystems. Moreover, decades of experience and research teaching functional programming have produced effective didactic approaches that enable anyone into programming to easily get into FP. The time to get started is now!
