OOP and FP

Explore the complementary nature of Object-Oriented Programming (OOP) and Functional Programming (FP) in this 52-minute Devoxx conference talk. Debunk common misconceptions about OOP and FP, understanding their strengths and how they can coexist in modern software development. Learn about polymorphism and encapsulation in OOP, as well as immutability and declarative style in FP. Discover how experienced developers can leverage both paradigms to choose the best approach for specific problems. Gain insights into topics such as decomposition, error management, and the differences between imperative and declarative programming styles. Examine practical examples comparing OOP and FP implementations, and understand key concepts like referential transparency and functional purity.

What's the difference?
Biggest OOP advantage: Polymorphism
OOP vs FP Decomposition
OOP Decomposition
Which one is better?
Composition(?)
Biggest FP advantage: Immutability
(im)mutability - OOP vs FP
Referential transparency means no side-effects
OOP vs FP Error Management
Use Exception only Exceptionally
OOP: FP = Imperative: Declarative
