> Mainly it was Crystal, Elixir or Go [as an alternative to Ruby].<p>You explain why you liked Go; did you try writing a microservice in all three languages and compare and contrast the process of writing, debugging, and supporting? I realize that's a tad unrealistic though I suspect _someone_ has done it. I'm personally looking at Elixir (coming from a .NET background) and am very aware of Go... perhaps I'll do the "one service, three languages" and give my thoughts on .NET Core, Go, and Elixir. Unless this has already been done... if so, someone drop a link pls!
