Kotlin

VMP
Kotlin (Ко́тлин) — это статически типизированный язык программирования, работающий поверх JVM и разрабатываемый компанией JetBrains. Также компилируется в JavaScript и в машинный код через инфраструктуру LLVM. Язык назван в честь острова Котлин в Финском заливе, на котором расположен город Кронштадт. Компания Google в 2017 включила Kotlin в официальный инструмент разработки Android Studio(JetBrains).
