This series on Scala aims to bridge the gap between theory and practice by focusing on something that is not easily found on the open internet: Actual examples of functional concepts being used in production, at scale. We’ll even give you code samples!

Part 1 of the series dives into something that’s near and dear to all of us: How to incorporate error handling as a primary concern with a minimal level of effort.
