About the Book

In compact chapters, concentrating on the essentials, you'll get to know Kotlin within a few afternoons or some subway rides, and you'll soon be able to use it to write your own programs and apps.

"Kotlin Compact" is officially endorsed by JetBrains, the creators of Kotlin itself, on their "books about Kotlin" page!

As the title suggests, "Kotlin Compact" is not explicitly an all-encompassing work on Kotlin. Rather, it focuses on the necessary foundations and best features Kotlin has to offer, and which are most valuable when getting started with Kotlin development.

About the Author

Thorsten Schleinzer
Thorsten Schleinzer

My name is Thorsten Schleinzer, I am a graduate in Media Information Technology and have been a professional software developer and architect for over 20 years.

For a long time I have been working intensively with different programming languages.

I started with BASIC, got to C/C++ via Pascal/Delphi & Assembler and finally arrived at Java.

Although I've been developing with Java since its version 1.2, I've been working with or am still using several other languages: C#, PHP, JavaScript/TypeScript, Ruby, Dart, Lua, Scala, and a few more.

But it was only with Kotlin that a new language was able to fully delight me and convince me of a change.
