Concurrency in Scala: Futures, Actors and Monad IO

The JVM, and Scala in particular provides several ways to run multiple tasks in parallel. I will detail the main ways to deal with parallelism in Scala: Futures (part of the standard library), actors (using Akka in particular) and more recently several libraries implementing the Monad IO inspired by Haskell (we’ll use cats effect as an example).
