#79 - Domain-Driven Design With Functional Programming - Scott Wlaschin

“It is good to improve your processes to make them faster and more efficient. But sometimes what’s even more important is doing the right thing in the first place."

Scott Wlaschin is the author of “Domain Modeling Made Functional” and the popular F# site fsharpforfunandprofit.com. In this episode, Scott began by sharing his view of the need for developers today to become more polyglot developers and learn multiple programming languages. Scott then shared about functional programming (FP) fundamentals and how FP differs with object-oriented programming, as well as cases when one is better suited than the other. Scott then explained how we can use FP when implementing Domain-Driven Design (DDD), including how to model some of the DDD tactical designs and transaction boundary. He also shared why F# is his favorite and go-to programming language. Towards the end, Scott touched on important advice about effectiveness vs efficiency, and what leaders need to be aware of regarding doing the right thing.
