## ScalaFP: Firsthand With Scala-Cats Monads – #1

Reading Time: 4 minutes In the previous post, we had a look at the reasons behind the monads and how monads can help us design the programs in a functional style. Now we are going to explore some of the monads which are frequently used in the applications but not available within the Scala predefined libraries. We will be exploring the monads which are provided by the scala-cats functional Continue Reading

## ScalaFP: Welcome To The World Of Functors

Reading Time: 4 minutes 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. First let’s explore function composition: Function Composition:  In this diagram, we have 3 sets called A, B, and C. Set A contains an element called x. Suppose, we need to convert our Set A elements into Set C. But we have no Continue Reading

## ScalaFP: Understanding Monoids In Scala Pragmatically

Reading Time: 3 minutes 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 were remaining from our previous post, : How can we use monoids with Scala? Where do we require Monoids? Now let’s answer these questions one Continue Reading

## ScalaFP: Let’s Begin With Monoids

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
