The Kotlin language has been around since 2011, but its popularity took off in 2017 when Google announced Kotlin’s inclusion as a first-class language for Android development. In 2019, Google announced a “Kotlin-first” approach to Android development. With modern and expressive language characteristics such as those found in Apple’s Swift, and 100% interoperability with Java, it’s no wonder that Kotlin has been named a top 5 most-loved language by Stack Overflow users.

If you’re a complete beginner to programming, this is the book for you! There are short exercises and challenges throughout the book to give you some programming practice and test your knowledge along the way.

Through Kotlin Apprentice, you’ll learn about basic things like constants, values and types, move up to more complicated items such as data structures, classes and enumerators, and finish off with some in-depth knowledge about functional programming, coroutines, and Kotlin Multiplatform.
