Implicits, type classes, and extension methods, part 3: conversions and implicit-based patterns

Is there any use case for implicit conversions? A reason why they were not removed completely?
Mateusz Kubuszok (@MateuszKubuszok)
Shared State in Functional Programming

Newcomers to functional programming (FP) are often very confused about the proper way to share state without breaking purity and end up having a mix of pure and impure code that defeats the purpose of having pure FP code in the first place.

Demystifying Dependency Injection with Airframe

Airframe is a library of lightweight building blocks for Scala, which simplifies these programming concerns, and helps us to reduce the number of things to consider when building applications.
Taro L. Saito (@taroleo)
Scala Wars: FP-OOP vs FP

FP follow-up to the discussion on "why IO", from the perspective of ZIO author
John de Goes (@jdegoes)
Why Scala?

Why would you consider using Scala? What are the technical and business reasons to use the language?
