What is Kotlin
Kotlin is a modern, statically typed programming language that runs on the Java Virtual Machine (JVM) and can also be compiled to JavaScript or native code. It was created by JetBrains and officially released in 2016. Kotlin is designed to be fully compatible with Java, offering a more concise and expressive syntax that improves productivity and code safety.
Key Features of Kotlin
