Kotlin, a language fully interoperable with Java, is rising in the ranks. Each month, TIOBE Software ranks 100 programming languages by their popularity with the programming community.

Google today announced the first preview of Jetpack Compose, a new open-source UI toolkit for Kotlin developers who want to use a reactive programming model similar to React Native and Vue.js.
