What is Kotlin mainly used for?

It is widely used to develop Android application . Kotlin is designed to interoperate fully with Java, and the JVM version of its standard library depends on the Java Class Library, but type inference allows its syntax to be more concise. Kotlin mainly targets the JVM but also compiles to JavaScript or native code.

There are many uses of Kotlin now. As far as programming language goes, it’s mature enough to be used in production. Being a developer I have seen two major use case of Kotlin outside of Android Development: Server-side Backend Development .

Kotlin is a programming language statically-typed for OSS, developed by JetBrains. It is mainly used for Android development and is an open-source PL. Besides this Kotlin is also used for writing Gradle plugins . After compiling it to the JVM, you can even use it for backend development or wherever java is used.
