Types, Kinds and Type Constructors in Scala | Rock the JVM

Written version: https://blog.rockthejvm.com/scala-typ... Links from the video: Some hard stuff about generics:    • Contravariance in Scala: Why Is It So Hard...   This video is for the mature Scala developer. We discuss how types are organized in Scala so you can think about them clearly. We introduce the concept of a kind (= a type of types) and type constructors. We use Scala generics a lot, including higher-kinded types. We'll end the video with the reason why we might want these Scala concepts in our mind and how they can help.
