@ RubyConf Mini 2022

Have you ever felt curious towards functional programming (FP)? Were you, soon afterwards, intimidated by the mystic terms like monads and functors?

This talk will walk you through the powerful mental models and tools that FP gives us, and how we can readily use them to improve our apps in a language that we all love and understand.
