Kotlin is a modern, statically typed language that runs on the Java Virtual Machine (JVM) and can also be compiled to native code or JavaScript.
It is designed to be concise, expressive, interoperable, and safe. Kotlin is mainly used for Android development, but it can also be used for web development, desktop applications, and server-side programming.
About
It has a concise and readable syntax that reduces boilerplate code and supports many features such as lambdas, coroutines, data classes, and extension functions.
It is fully compatible with Java and can use any existing Java libraries, frameworks, and tools. You can also mix Kotlin and Java code in the same project, making it easy to migrate from Java or use Kotlin alongside Java.
It has a powerful type system that supports null safety, generics, and smart casts. It also has a built-in DSL support that allows you to create domain-specific languages with ease.
It has a rich set of tools and IDE support, especially in Android Studio, which provides code completion, debugging, testing, refactoring, and more.
Here is an example of Kotlin
fun main() {
println("Hello, World")
}
