Reading Time: 2 minutes Today we are going to deep dive into the Scala Cats again to find out about Monoids. If you haven’t already read my post about Diving into Scala Cats – Semigroups I suggest you do so now. What are Monoids? The Monoid extends Semigroup and adds a default or fallback value for the given type. Monoid type class comes with two methods – one is the combine method of Semigroups, Continue Reading
Reading Time: 2 minutes Diving into Scala Cats – Semigroups
Reading Time: 2 minutes Knoldus Inc is proud to announce the launch of program “Back2Basics”. Back2Basics is our effort to add value to the Scala ecosystem by exploring not so explored concepts in Scala. The idea behind the inception of the program is to develop an understanding of Scala concepts that are hard to understand and not frequently used by developers. In this program, we have two parallel tracks Continue Reading
Reading Time: 2 minutes As we discussed in our semigroups post, monoids are also kind of functional design patterns. Most of the FP beginners are always confused between Monads and Monoids. According to them both are the same, Is It? In this post, we will be trying to learn “what monoids are according to mathematical terms?” For this, we just require the basic mathematical knowledge. Monoids The one line definition of Monoid Continue Reading
Reading Time: 3 minutes 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 require to use semigroups? First, let’s try to figure out, when and where we require semigroups in our code and during this we will automatically Continue Reading
Reading Time: 3 minutes 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 and when“. We are facing the same issue but after digging into it, we conclude that first step is to clear the concepts of “semigroups“, Continue Reading
