## 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

## ScalaFP: Understanding Semigroups In Scala Pragmatically

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

## ScalaFP: Let’s Begin With Semigroups.

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

## Understand closures in javascript

Reading Time: 2 minutes Let’s learn closures today, How closures are define how they got intialize and how they work A closure is a function within a function that has access to the environment that it was created, which gives the ability to access the private methods of outer function to their inner function. In simple words function which is return by another function called closures. A closure is Continue Reading
