Kotlin overview

Kotlin is a concise, statically-typed, multi-paradigm language that runs on the JVM, in the browser (Kotlin/JS), and as native binaries (Kotlin/Native). Developed by JetBrains, it became the preferred language for Android development in 2019. Key features include null safety, coroutines for async programming, extension functions, data classes, sealed classes, and a powerful standard library. Kotlin Multiplatform (KMP) allows sharing business logic across Android, iOS, and the web. On the server side, Spring Boot and Ktor are common frameworks. It is fully interoperable with Java.
