What is Kotlin? Nedir?
Kotlin is a modern programming language developed by JetBrains and adopted by Google as the official language for Android.
Kotlin was announced by JetBrains in 2011 with its first stable release in 2016. Running on the JVM, Kotlin is fully compatible with Java and was designed to address Java's shortcomings. Google's declaration of Kotlin as an official language for Android development in 2017 catapulted its popularity. Modern features like null safety, extension functions, data classes, coroutines, and sealed classes make Kotlin a strong alternative to Java. Kotlin can compile not only to JVM but also to JavaScript (Kotlin/JS), native code (Kotlin/Native), and WebAssembly. Kotlin Multiplatform (KMP) enables sharing business logic across iOS, Android, web, and desktop. Jetpack Compose supports modern Android UI development. Kotlin is now the primary language for Android development; most new Android projects start with Kotlin. Its use in server-side development with Spring Boot is also growing. Apps like Pinterest, Netflix, Uber, and Trello use Kotlin.
