Semigroups and Monoids in Scala

An introduction to semigroups and monoids in Scala, explaining these abstract algebra concepts and their practical applications in functional programming.

That said, the concepts of Semigroups and Monoids are transferrable to other languages as well. In this video we'll look at Semigroups and Monoids, two abstractions for functional programming derived from abstract algebra. We'll see how they would look like in Scala, and then we'll see what kind of practical problem they solve (besides adding more abstract math to programming). In the meantime, we'll also see some good practice for organizing Scala code, in the same style as the Cats library is organized. The video is shot in Scala 3, but the concepts are equally valid for Scala 2 (and the article shows the Scala 2 implementation as well).
