Kotlin has established itself as a modern, versatile programming language, particularly strong in Android development where it is the preferred language recommended by Google. Its concise syntax, null safety, and seamless interoperability with Java make it a popular choice for backend development as well, especially within the JVM ecosystem. While Kotlin Multiplatform is still maturing, it offers promising capabilities for cross-platform mobile and shared codebases. Although Kotlin's usage is limited in fields like data science, systems programming, and frontend web development, its continued evolution and strong tooling support from JetBrains ensure it remains a relevant and valuable language in the modern software landscape.
