Kotlin! :) Which incidentally added coroutines and async/await in the recently released version 1.1.

Server-side (running on the JVM): http://kotlinlang.org/docs/reference/server-overview.html

Compiling to JavaScript for the client side: http://kotlinlang.org/docs/reference/js-overview.html

...and for the Android client, compiling to Java bytecode, using the regular Java-based Android APIs and SDK: http://kotlinlang.org/docs/reference/android-overview.html

For iOS and other targets where you don't want the Java or JS runtimes, native compilation via LLVM is in the works: https://github.com/JetBrains/kotlin-native/
