Why you should learn Kotlin ?
At recent Google I/O held on 17 May 2017, the Android team announced Kotlin as an official language for Android apps development.
Many companies like Netflix, Uber, Trello, Pinterest, Corda etc. are using Kotlin (along with other programming languages) to create applications.
The number of lines of code increased from 2.1 million to 10 million in an interval of one year (2016 to 2017).
Though the majority of progress has been made on Java and Android, it’s not a Java/Android language. It can compile many Kotlin projects to JS. Similarly, Kotlin/Native is under progress that compiles Kotlin directly to machine code.
