The 4 Rules of Simple Design in Functional Programming

Explore the application of the 4 Rules of Simple Design in Functional Programming through this 47-minute conference talk by Uberto Barbini at Devoxx. Trace the evolution from Procedural to Object-Oriented languages, and now to the era of Functional Programming. Discover how category theory, a mathematical tool-set, can aid in functional design. Learn how the 4 Rules of Simple Design and Test-Driven Development (TDD) from Object-Oriented Programming can be effectively applied to Functional Programming. Examine concrete examples from real-world scenarios that demonstrate how these rules harmonize with functional programming concepts. Gain insights into how categories, functors, and natural transformations can naturally emerge from code, and understand how comprehending these concepts can lead to improved design in functional programming.
