Explains the basic and even rather complicated concepts really well, using many examples from real software.
An excellent book for developers to know more about Kotlin. It assumes some Java experience for the readers. If you haven't already known some Kotlin before, I'd say this book is perfect for you to get started.
I already knew some Kotlin and would like to delve more into the advanced topics. So I skimmed through the first half of the book which is the foundations and focused on the second half explaining the type system, lambda, DSL, reflections of Kotlin.
Overall I found the author explaining with clarity and structure, a style I absolutely enjoyed. Some topics are left to be desired, such as Kotlin Native, coroutines, and metaprogramming.
