Functional Programming Crash Course for Scala Beginners

FP in Scala in one video: immutability, lambdas, monads, tagless-final (TF), effect types and effect type libraries like monix, cats-effect and ZIO. It's a crash so we will move fast and won't dive into recursion this time since it's rarely used in production applications. This is a follow-up to this video, which is for experienced Scala devs: https://youtu.be/RaQnGCGmWI4
