The Book Of JOSH Scala In The Enterprise from The Grey Lens Man's View
Fast forward… Currently a very small team and myself are near completion of the first major functional component on the JOSH stack.
All of the development talent on the team are experienced Java developers. And they have been effective from Day 1.
No real discussions of covariance and contravariance was required. We did discuss HOF, anonymous lamba, closures, cut syntax, maps, folds, reduces. And strangely their heads did not explode. We did discuss the evil of mutable state, and referentially transparent functions.
They were enthralled.
