Kotlin

A statically typed language for Android, backend, and multiplatform applications

Meet Kotlin

Kotlin is an open-source, statically typed programming language for Android apps, backend services, and applications that share code across platforms. It works with existing Java libraries and code, allowing teams to introduce Kotlin gradually into JVM projects. Its type system distinguishes nullable values from non-null values, helping developers catch common mistakes before a program runs. Coroutines provide a structured way to write asynchronous operations without blocking a thread while waiting.

With Kotlin Multiplatform, developers can share business logic across Android, iOS, desktop, and web applications while retaining access to native platform APIs. Teams can keep separate native interfaces or share UI with Compose Multiplatform. Kotlin is supported in IntelliJ IDEA and Android Studio, and its browser-based tour offers a practical starting point for learning the language.
