Embark on a journey through programming history and functional paradigms in this conference talk from NDC Melbourne 2022. Explore the reimagining of the iconic 1971 computer game "Oregon Trail" using functional C# programming techniques. Discover how to achieve near 100% unit test coverage, implement immutable variables, and minimize the use of traditional programming statements. Gain insights into advanced functional programming concepts such as higher-order functions, functional flows with simple Monads, and tail recursion. Enjoy a blend of retro computing nostalgia and modern programming practices as the speaker demonstrates how to recreate a classic game while adhering to functional programming principles in C#.
