Kotlin is a modern, statically-typed programming language that runs on the Java Virtual Machine (JVM) and is fully interoperable with Java. Developed by JetBrains, Kotlin offers a concise and expressive syntax, reducing boilerplate code and enhancing productivity. It supports various programming paradigms, including object-oriented and functional programming, and provides features like null safety, extension functions, and coroutines for asynchronous programming. Kotlin's seamless integration with existing Java codebases, along with its enhanced safety and performance features, has led to its widespread adoption, particularly for Android app development. Endorsed by Google as the preferred language for Android development, Kotlin continues to grow in popularity due to its simplicity, versatility, and powerful capabilities.
