Since its announcement as an officially supported language for Android, Kotlin has experienced a huge rise in popularity. This proliferation in popularity is in many ways warranted as Kotlin is a modern and extremely well-designed language, which has many domains of application—web, mobile, and native to name a few. As a direct consequence of its rise in popularity, Kotlin has experienced steady growth over the years.
This book will be useful to readers of all ages, experience levels, and demographics. That being said, it was written primarily with beginners and experienced programmers who want to learn Kotlin in mind.
Over the course of writing this book, I paid special attention to the fact that beginners will need to be eased into topics and concepts. As such, the chapters of this book were written in ascending order of difficulty. If you are a beginner, this will enable you to learn as quickly as possible with as few hiccups as possible.
Fairly experienced readers are expected to move more quickly through this book than beginners—all things being equal. If you have prior experience of programming and application development, you may choose to first run through the code examples of this book to get a good feel for the topics covered and what to expect. Java developers in particular may be able to get away with diving right into the more advanced chapters of the book.
Regardless of which category of user you fall into, rest assured that there is something that has been written specially for you!
