Implementation of the Load Balancer exercise for IpTiq.

Install the Scala Build Tool.

Build using:

sbt compile

and test using:

sbt test

A state monad encode changes in state. This makes systems more testable and easier to compose. This implementation uses a very minimal implementation, but is still fully functional.

That would work as well, although in highly concurrent systems working without specific state makes it more difficult to reason about correctness. The ZIO libraries use the Ref Monad as its primary structure to communicate about state.

In addition, using the State monad we can automatically generate programs and test them for correctness using property based testing with libraries such as ScalaCheck
