Most simply, jank is a Clojure dialect on LLVM with C++ interop. Less simply, jank is a general-purpose programming language which embraces the interactive, functional, value-oriented nature of Clojure and the desire for the native runtime and performance of C++. jank aims to be strongly compatible with Clojure. While Clojure's default host is the JVM and its interop is with Java, jank's host is LLVM and its interop is with C++.
jank is currently in alpha! Look here for details.
