Kotlin: An Illustrated Guide

The fun way to learn Kotlin programming, one concept at a time!

Who is this book for?

If you’re interested in learning Kotlin development, this book is for you. Everyone has a unique experience - some readers are new to software development entirely, some are new to Kotlin development, and some are existing Kotlin developers who want a deeper understanding of certain language concepts.

My approach in this book is to explain Kotlin programming concepts with simple, tangible, and illustrated examples, so that regardless of your experience level, things will make sense. I do my best to define terms clearly before using them, so that as you read the book, you’ll build upon a solid foundation of existing knowledge rather than an uncertain, tenuous foundation of ambiguity.

Even if you already know some of the concepts presented in this book, my goal is to give those concepts such a fun and vivid presentation that you’ll enjoy reading about them again, which I hope will give you a definite clarity about them, shining light on the foggy corners of concepts that you might have wondered about.

What’s the current state of this book?

This book is in active development. Chapters 1-15 are complete, and I’m expecting to have a total of about 20 chapters. My main focus at the moment is to complete the remaining chapters. After that, I’ll plan to refine some of the artwork in earlier chapters for even better resolution for the PDF format.
