Kotlin is a cross-platform, statically typed, general-purpose high-level programming language with type inference. This tag is often used alongside additional tags for the different targets (JVM, JavaScript, native, etc.) and libraries/frameworks (Android, Spring, etc.) used by Kotlin developers, if the question relates specifically to those topics.
Kotlin is a concise multiplatform language developed by JetBrains and Contributors.
It supports JVM bytecode, JavaScript, and Native code as compilation targets, and it has been an officially supported first-class language on Android since Google I/O 2017. The goals with Kotlin are to make it concise, safe, versatile and multiplatform, providing seamless interoperability with existing Java libraries.
On May 23rd 2024, the JetBrains team released version 2.0 (announcement / github release tag).
The current major version is 2.0.0.
How to ask
