It's clear to everyone that Kotlin is an object-oriented programming language. And its large number of built-in features makes Kotlin open to different paradigms. Particularly, Kotlin follows a functional style that brings a lot of new approaches that weren't available before for Java developers.
Object-oriented programming is ideally suited for modeling domains and representing real-world objects. Functional programming can elegantly pack a lot of actions into a few lines of code. Moreover, the concepts of immutable objects and pure functions from functional programming make scaling a program in a multi-core environment much easier.
Kotlin is a programming language that combines these approaches and lets you describe the behavior of objects flexibly.
In this chapter, we'll cover the following topics:
- Functional programming
- Inspecting functional...
