ABOUT KOTLIN

Kotlin is a powerful and extensible programming language created by Jetbrains, the same company that created IntelliJ Idea which powers Android Studio today. During Google I/O 2017, Google announced that Kotlin would become a first-class citizen on the Android platform, and here we are! There are almost no reasons not to learn the language now.
