Kotlin: How to Do Higher-Order Functions

In this article, I want to show you from a beginner perspective how a programmer can implement higher-order functions in the beautiful language Kotlin! I tried to write my code snippets in a way that you can just copy and paste it in your preferred IDE and test it by yourself.

Of Course, it has nothing to do with Star Wars 😄

What are Higher-Order Functions?

Are you already using them? Though the term higher-order may sound fancy and complicated, it is actually much simpler than you’d think. In fact, you have probably already used higher-order functions without even realizing it. A higher-order function is a function that either takes a function or functions in as an argument or returns a function. All other types of functions are considered first-order functions. Because JavaScript accepts higher-order functions, that is what makes this programming language suitable for functional programming.
