LiveScript is a functional programming language that transpiles to JavaScript.

It was created by Jeremy Ashkenas—the creator of CoffeeScript—along with Satoshi Muramaki, George Zahariev, and many others.

(The name may be an homage to the beta name of JavaScript; for a few months in 1995, it was called LiveScript before the official release.)
