Scala

Lichess is amazing Chess service that's built with Scala. Scala Bootcamp & Rock the JVM courses are nice.

Notes

• Scala enables abstractions which aren’t possible and/or not nearly as elegantly expressed in Kotlin due to for example the lack of native higher-kinded type (HKT), typeclasses, structural intersection/union type lattice, operator overloading, path dependent types and robust pattern matching in Kotlin (and probably many other nuances such a value types which are ostensibly useful for example for efficiently emulating new type system features)
