Explore functional architecture and its inherent advantages in a conference talk that contrasts object-oriented and functional programming paradigms. Discover how functional programming naturally leads to best practices that require deliberate effort in object-oriented design. Learn about pure functions, port and adapters, encapsulation, domain-driven design, and how these concepts align with functional programming principles. Examine a restaurant reservation example to understand the benefits of pure functions and concentric circles in system design. Delve into testability, discussing how functional programming mitigates test-induced damage and promotes easier unit testing through higher-order functions and natural isolation. Gain insights into writing pure functions and how they contribute to more maintainable and robust software architectures.
