Mini Course: Functional Programming

Functional programming (FP) is a programming paradigm where programs are constructed purely from function. FP programs tend to look different from their imperative counteparts and have a lot of interesting properties.

FP languages such as Haskell, Common Lisp, Scheme, Clojure, Erlang, Elixir, Elm, F# and more are used in a variety of fields. Recently, a lot of FP features have made their way into imperative languages such as Java, C++, Python, JavaScript and more. 

I dare say that learning FP concepts will make you a better programmer, regardless of your language of choice. In this course, we will cover some of the core concepts of FP using Haskell as an example.

Target audience

This course is suitable for people with prior experience in programming (in any language). 


The teachers will be Vsevolod "Seva" Nikulin (PhD Student in Tani Unit) and Jeremie Gillet (FP Enthusiast).


The program will be a combination of lectures and exercises with Haskell (using ghci as a REPL and a code editor of your choice).
