We can easily model things with classes and OOP, we can pull in functional libraries and model everything with functions and values, we can implement a stateless monolith or a distributed system. And today we have a lot of books and tutorials that cover these topics: how to glue the code together to create a maintainable application with raw Futures/Akka/Cats ecosystem/Zio ecosystem/Scala as typed Python.| kubuszok.com

Concurrency requires little effort as you don’t have to be worried about locking, mutexes and semaphores - nobody can change your data anyway. If you need to update something you can just create an updated copy and use it for now on. Except if you have a nested structure and need to update something deep, deep inside.| kubuszok.com
