ScalaFP: Welcome To The World Of Functors


In functional programming, we have various pillars like Functors, Monads, Applicative and more. Today we will try to explore one of these pillars called Functors. Before moving to functors, first let's explore function composition: Function Composition:  In this diagram, we have…

ScalaFP: Understanding Monoids In Scala Pragmatically


As we discussed in our previous post, Monoids are semigroups meaning they have properties called closure and associative, along with identity element. So, now our question is, why do we require the identity element? Let's add this one to our questions which…

ScalaFP: Understanding Semigroups In Scala Pragmatically


In our previous post, we discussed semigroups according to mathematics and we conclude that semigroups have two properties called closure and associativity. But still, we have some questions like: How can we use semigroups by using Scala? Where do we…

ScalaFP: Let’s Begin With Semigroups.


While we start looking into functional programming, the first thing we find out is "Category Theory" and if you are not a mathematician, then, it is really a huge pain to find out the answers to questions like "what, how…
