Let's look at type manipulation in Scala...

At Scala World, Senior Systems Engineer Joe Barnes helped us to get motivated with a new comfort level in types so we can take the plunge into the riches of one of Scala's greatest features!

 

Typelevel Programming 101: The Subspace of Scala

Scala boasts a powerful type system which assists developers in writing and maintaining bug-free software. Unfortunately, many members of the growing Scala community struggle to utilize the Scala type system due to prior experience with poor static type systems or none at all. 

This talk aims to narrow the gap between haves and have-nots of typelevel programming by teaching some basics of type manipulation in Scala. 

This presentation is the product of my journey into the Scala type system from a background in Java. I will review the familiar value-level runtime programming, and show how the same logic can be utilized at compile time via the type system. As the title suggests, this is an introduction; no theoretical background knowledge is required. 

By the end of the talk you will be motivated with a new comfort level in types enabling you to take the plunge into the riches of one of Scala's greatest features.
