Haskell Beginners 2022 Course Announcement

December 8, 2021

I’m offering a free beginner-friendly Haskell course!

In this course, I’m going to explain the fundamentals of Functional Programming (FP), Haskell Syntax and teach you skills for solving problems in the functional style. No prior knowledge of FP or Haskell is required!


The course starts on January 10 (Monday), 2022 and comprises four 1-hour lectures on four consequent weeks. Specifically, the times of lectures:

  • Lecture 1: Jan 10 (Monday), 19:00-20:00 (UTC+0)
  • Lecture 2: Jan 17 (Monday), 19:00-20:00 (UTC+0)
  • Lecture 3: Jan 24 (Monday), 19:00-20:00 (UTC+0)
  • Lecture 4: Jan 31 (Monday), 19:00-20:00 (UTC+0)


I’m planning to record lectures and may even stream them on YouTube so they’ll be available later.

In addition to lectures, the course contains practical exercises that you can complete and get my feedback on your solutions.

I’m going to cover the following topics:

  • What is FP?
  • Lazy evaluation
  • Immutability
  • Higher-Order Functions
  • Algebraic Data Types (ADTs)
  • Pattern-matching
  • Parametric polymorphism
  • Ad-Hoc polymorphism
  • Haskell Syntax
  • Standard Haskell data types (Maybe, Either, Lists)
  • Typeclasses
  • Functor
  • Applicative
  • Monad
  • IO
  • do-notation

The final goal of this course is for you to be able to write a simple program in Haskell that interacts with the real world (e.g. search a substring in a file, count the number of files with the specified extension, etc.).

If you complete all home exercises by the end of the course you get enough Haskell knowledge to start solving real problems. You’ll also receive a pretty PDF certificate about the course completion 💝

What do I need for the course?

To attend the course, you need:

  • Zoom account. Lectures will be given via Zoom.
  • GitHub account. Home exercises will be found and verified on GitHub.
    • As a consequence, some basic git knowledge is required: forking repositories, committing changes and pushing them.
  • Telegram account (optional). A Telegram group will be created for all participants to discuss the course, exercises and solutions.

How to apply?

If you’re interested in listening to the course and doing exercises, apply using the following form:

Privacy notice: I won’t share your applications with anyone.

I especially encourage minorities in tech to apply. They’ll be given a preference during the attendees’ slot allocation. However, you’re not forced to disclose any specific details about yourself (or any details at all).

I’m planning to give the course to a maximum of 100 participants. However, I’ll give the course anyway even if only a single person applies.

The application form closes on December 30.

I’ll send emails with application results by January 2, 23:59:59 (UTC+0).

How much should I pay for the course?

Nothing. The course is free to apply and attend.
