Dave Farley explores the history, trade-offs, and core differences between object-oriented and functional programming paradigms.

Object-Oriented Programming has been the dominant approach for the past couple of decades, but Functional programming languages are growing in popularity and influence. So is OO programming outdated? Is Functional programming a fashion that simply misses the point? Many Functional programmes think that Object Oriented programming is bad. Many OO programmers think that Functional Programming is not scalable, what is the truth? In this episode, Dave Farley explores the software engineering question of object-oriented vs functional programming. Where did these ideas come from, what do they mean and why do they matter. Also, are there other ideas that may be coming in future? ------------------------------------------------------------------------------------- Also from Dave: 🎓 CD TRAINING COURSES If you want to learn Continuous Delivery and DevOps skills, check out Dave Farley's courses ➡️ bit.ly/DFTraining 📧 Get a FREE guide "How to Organise Software Teams" by Dave Farley when you join our CD MAIL LIST 📧 The best way to keep in touch with the latest discussions, events and new training courses, get FREE guides and exclusive offers. ➡️ subscribepage.com/organise-teams-guide ------------------------------------------------------------------------------------- 📚 BOOKS: 📖 Dave’s NEW BOOK "Modern Software Engineering" is now available on Kindle ➡️ amzn.to/3DwdwT3 In this book, Dave brings together his ideas and proven techniques to describe a durable, coherent and foundational approach to effective software development, for programmers, managers and technical leads, at all levels of experience. 📖 "Continuous Delivery Pipelines" by Dave Farley paperback ➡️ amzn.to/3gIULlA ebook version ➡️ leanpub.com/cd-pipelines 📖 The original "Continuous Delivery" book by Dave Farley and Jez Humble ➡️ amzn.to/2WxRYmx ------------------------------------------------------------------------------------- CHANNEL SPONSORS: Equal Experts is a product software development consultancy with a network of over 1,000 experienced technology consultants globally.

On “Looking for resources about popularity of functional programming”

Not sure if they count as credible sources for your needs, but I enjoyed these talks on this subject: "Why Isn't Functional Programming The Norm?" (Richard Feldman, Clojure 2019) "Object Oriented Programming vs Functional Programming" (Dave Farley) "Functional Programming is Terrible" (Rúnar Bjarnason, NEScala 2014)

On “I have a question... about OOP vs FP (I know, I know)”

I literally just watched a video about this last night, and I think the author has a very good, balanced perspective on the subject. [Continuous Delivery - Object-Oriented Programming vs Functional Programming (YouTube)]

Don't Shoot Yourself in Your Foot I just watched this video by Dave Farley (YouTube has a way of informing me of interesting stuff): link to this video time: 00:18:54 In it he talks about the early efforts at programming and how OOP and FP came to be. He refers a bit to assembler and asynchronous stuff. I think there are two parts to why certain ideas gain traction and Farley leans toward performance while I look a lot at ergonomics. He says he agrees to some extent with Robert Martin's idea that language features (like type checking) are intended to constrain us, so we can't shoot ourselves in the foot. There are various reasons for adoption of language features. He also explains some of the early…
