Kotlin Programming Language Tutorial
Overview
Kotlin is a modern, statically typed programming language developed by JetBrains. It is 100% interoperable with Java and can run on JVM, Android, browser, and native platforms. Kotlin is known for its concise syntax, null safety features, and powerful coroutine support.
