Best Kotlin Books: What is Kotlin?
Kotlin is a relatively new (2010) open-source, cross-platform programming language.
Itâs both an object-oriented and a functional programming language.
Kotlin is 100% interoperable with Java. So you can call Kotlin code from Java and vice versa.
When compared to Java, thereâs approximately a 40% reduction in the number of lines of code.
Kotlin is primarily used in Android development.
Did you know that Kotlin can be used for server-side development?
Now letâs get into the best Kotlin books for 2021âŚ
