Kotlin is a modern, statically typed programming language used for Android development and interoperable with Java.
Backed by Google as the preferred language for Android apps, Kotlin simplifies common development tasks with concise syntax, null safety, and functional programming features. It reduces boilerplate code and integrates easily into existing Java-based projects.
Kotlin is used in apps from startups to global platforms like Pinterest and Netflix. It’s also expanding beyond Android — supporting web (Kotlin/JS), server-side development (Ktor), and even native app compilation (Kotlin Multiplatform).
