Go is a nice C like language which uses Composition over inheritance. I implements go routines and channels which make asynchronous processing feel natural and easy to control.
Since it's typesafe and has a really small set of commands it's a really good tool language for devops.
It was built with the intention to eliminate race conditions so it makes concurrency esp easy.
As well as the interface on structs are awesome I like that it takes away the OO mania a little and build things around data not functionality.
It's a nice tool language :)
