Blog 4 – OOP to Functional Programming We are already using functional programming using Scala with the previous blog series of Self-Learn Yourself Scala in 21 Blogs (#1, #2, #3). Let’s start with defining functional programming which is a programming paradigm that models computation as the evaluation of expressions and expressions are built using functions […]
Blog 3 – Functional Programming & Data Structures In Scala Functional programming and functional data structures are very interesting and powerful. Actually it supports both types data structures called immutable & mutable. And let us discuss on two more vital concepts called type parameterization and higher-order functions. The type is similar to Java generics; it […]
