Youtube Summary

Statically typed functional programming languages encourage a very different way of thinking about types. The type system is your friend, not an annoyance, and can be used in many ways that might not be familiar to OO programmers. Types can be used to represent the domain in a fine-grained, self-documenting way.

And in many cases, types can even be used to encode business rules so that you literally cannot create incorrect code. You can then use the static type checking almost as an instant unit test — making sure that your code is correct at compile time. In this talk, we'll look at some of the ways you can use types as part of a domain-driven design process, with some simple real-world examples. No jargon, no maths, and no prior FP experience neces

When it comes to DDD, I highly recommend the book Domain Modeling Made Functional and the lectures the author has given based on the book: https://www.youtube.com/watch?v=9QlhkQl0DSw
Those two resources where the ones the led to really get and appreciate DDD. One thing I really liked about them is that all the examples are in F# (the functional part of the title) and so manages to make it clear how DDD and OOP are decoupled and how DDD doesn't necessarily imply OOP.

Can absolutely recommend watching that video.

I agree very much that DDD is an extension of OOP in many ways
May I recommend the video Domain Modeling Made Functional: https://www.youtube.com/watch?v=9QlhkQl0DSw
and the book on the same topic: https://pragprog.com/titles/swdddf/domain-modeling-made-func...
Scott Wlaschin has been on a "crusade" for years to decouple DDD from OOP and show that doing DDD in a functional language (he uses F# for all his examples) is not only possible, but preferable. He might not change your mind, but it will make you look at DDD from a new angle.

Scott’s talks on DDD and functional programming are great. He also published an excellent book, “Domain Modeling Made Functional.”

Seriously, if you haven't read his book I'd really recommend it. It's core concepts are surprisingly simple yet profound.
Applicable in functional languages and non functional languages. It still amazes me he isn't more well known.

I stumbled across one of his YouTube videos doing a DDD and EventStorming binge. I’d never heard of him prior. Definitely someone I watch for content from now.
