Kotlin

Kotlin

Kotlin is a modern, versatile and expressive language that combines Java's power with a more elegant syntax - ideal for everything from Android apps to server code and multiplatform development.

About Kotlin

Kotlin is JetBrains' love letter to developers who want the best of both worlds: full Java compatibility and a syntax that is cleaner and smarter. It's as if Java went to a spa and came back more relaxed. With features like null-safety, data classes and coroutines, it's easy to write code that is both robust and readable.

But Kotlin isn't just the JVM's new favorite. Thanks to Kotlin/JS and Kotlin/Native, you can compile to JavaScript or run directly on platforms like iOS and Linux. This makes it possible to share logic across platforms without rewriting everything from scratch. With Kotlin Multiplatform you can build apps that feel at home everywhere - from mobile to server.

So if you're looking for a language that combines pragmatism with modern design, Kotlin is an excellent choice. It's a flexible problem solver in code form - ready to meet almost any need.
