In January 2022 I was teaching a free Haskell course for complete beginners. No prior knowledge of Haskell was required. And I explained different various Haskell and FP concepts from scratch up to Monads and writing real-world applications in Haskell.
The course contains four 1-hour lectures. And they all are available on YouTube for free!

The course also contains exercises. So if you want to learn Haskell, you can watch the lectures and solve the tasks
Have fun learning Haskell!
