Kotlin REPL and Kotlin Playground

Not every experiment needs a full project. Kotlin REPL (Read–Eval–Print Loop) lets you type snippets and see results immediately inside IntelliJ: Tools → Kotlin → Kotlin REPL. For sharing or learning in a browser, Kotlin Playground (play.kotlinlang.org) runs code server-side with selectable Kotlin/JVM version and dependencies for common libraries.
