Kotlin is rapidly becoming a common programming language among Android developers. Officially supported for app development since last year, it is called to be an expressive, concise and powerful language given its improved quality code and performance.
Its interoperability makes it possible to add new features built in Java to your codebase. This can definitely make the transition easier for those developers willing to give Kotlin a chance.
We already made a list of books you can use to start your journey learning this amazing language, however, there are other multiple resources out there you could also find useful.
It is important to mention that Kotlin is not new, it’s been out there for almost seven years, so, a proper documentation is available for those who want to try this new code everyone is talking about.
