IO monad: which, why and how

Learn how it is better than your standard imperative approach, how it helps reason, encapsulate side-effects and design more elegant programs.

ZIO and Cats Effect: Reactive Streams for Functional Scala

Let’s take a look at my top 12 reasons why ZIO and Cats Effect are a match made in heaven!
