Supercharge Scala Future | FP-Tower - What Is an IO?

The video tutorial discusses the concept of actions in Scala, highlighting their non-deterministic nature and the need for retry mechanisms and exception handling. It explains how to design an interface for actions using traits and by-name parameters, comparing it to val and def functions. The tutorial emphasizes the benefits of using a trait for actions, such as offering a rich API and better documentation. It concludes with a discussion on naming conventions in Scala libraries, suggesting the use of conventional names like IO and unsafe run.
