CoffeeScript, which attempts to make it easier to program in JavaScript, has a newly released beta version that features ECMAScript 2015+ support.The currently downloadable 2.0 beta offers ES2015+ syntax, where ES2015+ is recognized as ECMAScript 2015 and later features.

ECMAScript is the official specification underlying JavaScript.
