Scott Wlaschin demystifies functional programming terms like monads, monoids, functors and catamorphisms by showing how they fit into a small toolkit. He applies them to problems such as missing data, list handling, and functional dependency injection.
Why Hacker News points people here: HN recommends it as the best beginner-friendly introduction to monoids, monads and other FP vocabulary.

Best introduction to monoids, monads and FP terms
On the same note, I recently shared a link[0] to his great beginner talk on functional programming languages. This was by far the best introduction to monoid, monads and few other functional programming terms. Direct youtube[1] for those who don't want to click twice :) [0]: link [1]: this video

Among resources for diving into functional programming
More of a comment on the author, I've found his other articles enlightening, useful as both introductions to functional programming ideas and as comprehensive deep dives demonstrating their intuitive nature both in code and contextual application. A lot of the articles in conjunction with some other resources[1][2][3] are great for diving into functional programming (I've watched and read these many times). If you do front end development with React, I highly recommend the following two videos[4][5] with Ryan Florence and Micahel Jackson (devs behind react-router and Remix) on the compositional nature of React components and hooks. The last note I'll add is, once you get into Functional Programming, you start wanting to use `compose` or its counter part, `pipe` everywhere and coding becomes a lot more fun. I'll put a final plug for one of my own posts on how composition manifests in Javascript/React code[6]. [1] link [2] link [3] this video [4] link [5] link [6] link
“WHY: The Functional Programmer's Toolkit - Scott Wlaschin”
Explains why to use functional programming, first step to learn Haskell
Learn Haskell in 1-2-3: 1) WHY: The Functional Programmer's Toolkit - Scott Wlaschin : this video 2) WHAT: Learn Haskell in one video : link 3) HOW: Haskell without the theory : link It'll teach you enough to be dangerous. Obviously your learning has just begun, but with a mental platform that lets you study other resources in time and practically test things out.
