An explanation of the famous category theory phrase, deconstructing monads, monoids, and endofunctors using Scala 3 without mathematical jargon.
Written form: blog.rockthejvm.com/monads-are-monoids-in-the-category-of-en… Twitter thread: twitter.com/rockthejvm/status/1379695298365300736 "Monads are just monoids in the category of endofunctors" is probably one of the most abstract, condensed, convoluted and misunderstood phrases in functional programming. In this video we'll deconstruct what that means, in Scala 3, with no math jargon, for the pragmatic Scala programmer.
