Kotlin v1.4.20 released, JVM-based programming language
1 min readKotlin is a statically typed, cross-platform, general-purpose programming language with type inference. 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 (via LLVM). Kotlin is sponsored by JetBrains, a software development company based in Prague, and is also backed by Google under the Kotlin Foundation.
Kotlin is officially supported by Google for mobile development on Android. Since the release of Android Studio 3.0 in October 2017, Kotlin is included as an alternative to the standard Java compiler. The Android Kotlin compiler lets the user choose between targeting Java 6 or Java 8 compatible bytecode.
