Kotlin is typically associated with Android development, and most discussions surrounding it gravitate around this. However, the language has much more to offer and is ideal for modern server-side developers. While any Android developer will find useful snippets in this book, it is primarily aimed at Java and Scala developers. The book starts with an introduction to Kotlin and explains how you set up your environment before moving on to the basic concepts. Once the basics are out of the way, the focus shifts toward more advanced concepts, and don't be surprised if you see a few bytecode listings. Once you have completed the book, you should have all the knowledge required to start using Kotlin for your next project.
