Kotlin is a cross-platform, general-purpose, and open-source programming language. It is a statically typed language that runs on JVM and can be used everywhere Java is used. We can use it to develop Android apps, server-side apps, and much more. It is emerging as the most highly adopted technology. It was developed by JetBrains and released in 2010 with a small project. The first official release of Kotlin came in February 2016. It was developed under the Apache 2.0 license. Kotlin has a special feature named "Kotlin Multiplatform" that can be complied with the JVM bytecode, JavaScript, or LLVM code. The scope of the app developed in Kotlin is unlimited.
