> TL;DR I am reading “Domain Modeling Made Functional” and discussing and keeping a journal of what I learned from it, any co-readers welcome because the topic alone is so interesting that I will get 4 times the fun if we chat about things here! F# or not, this is amazingly well-written and useful! [Here is the link (PragProg)](https://pragprog.com/titles/swdddf/domain-modeling-made-functional/) ![swdddf](https://forum.devtalk.com/uploads/default/original/2X/b/b32a65773c6fb5b270e7bcdd973e0736b44bf241.jpeg) Hello! I’m back. This is something I’ve been trying to do for awhile now. Domain Modeling Made Functional is one of the best books I have read on the topic. I read it when it got out but I did not know F# nor had I any interested in it, so I just read the concepts and translated whatever I felt I earned into Elixir or Python, or JS depending on what I was in the mood for on that day. During my (along with a friend’s) stunt of #100DaysOfCodeIn100Languages (started as a joke, got serious, now back a joke) I encountered F# on day/language 13, and I enjoyed solving the problem with it (I had C# earlier that had similar effect but not a saga-breaking one like F# had), I recalled I have a book on it so decided to give it another read. I picked the book up two weeks ago while travelling to Alberta, and ended up spending 3 of the 4 hours on aeroplane reading it, thoroughly impressed and enlightened! I felt like it would be more effective if done at a much slower pace, on different reference project, and discussing with friends! So here I am, having my third (second one didn’t fail, I will continue it soon) book club in this group. The routine’s regular, I read a chapter or two, and talk about what I learned and how it would influence how I reason about a unit of code that does something. If you join me, that’d help me more! Eitherways, I’ll treat it as a set of side-notes or scribble which would help me when I refactor a deserving monolith or give my next talk on DDD (It already helped in my 2018 PyCon Canada session). I will reset and restart from chapter 1 here, starting right now! ---

We’re excited to see these book clubs. Sending cheers from Prag! ---

How did you get on with this after Mafinar? Is it something that could translate easily to Elixir? ---

Ah I was searching for this thread. I ended up learning F# and loved it. So didn’t get to translate. Once I am done with the other book club on concurrent Elixir I’ll be back here treating it with Elixir. ---

As far as translation is concerned, maybe not 1:1 but a lot of ideas could be explained through Elixir in a more idiomatic way. This is what we shall figure out it seems 😉 ---

Heard a lot of good stuff about the book, I should probably add it to my reading list. 🙂 ---

Would it be an Elixir version? ---

Yes I always wondered if I could translate the book’s codes and concept to Elixir and make notes. A few concepts at the later half might be tricky but we’ll see 🙂 This could also be an excuse to try out libs like Domo and Commanded. ---

Does the book require knowledge/experience in F#? ---

No it does not in my opinion. When I read this book for the first time, I had no knowledge of F# and had taken most of the concept and applied those to Python. It wasn’t a perfect application on my part because my goal was preparing for a conference talk back then, but I certainly didn’t feel anything was missing due to my lack of F# knowledge However, I did know TypeScript at the time and also Python type hints have concept like Union Types, and those helped a little.
