OOP and FP - Complementary Techniques in Software Development

Explore the complementary nature of Object-Oriented Programming (OOP) and Functional Programming (FP) in this insightful 51-minute conference talk from Devoxx. Debunk common misconceptions about both paradigms and discover how they can coexist harmoniously in modern software development. Learn about the core strengths of OOP, including polymorphism and encapsulation, alongside FP's focus on immutability and declarative style. Gain a deeper understanding of message passing in OOP, decomposition techniques in both paradigms, and how to effectively manage errors. Compare imperative and declarative approaches, and examine different versions of functional programming implementation. Equip yourself with the knowledge to choose the right tools for specific programming challenges, ultimately enhancing your ability to create efficient and maintainable code.
