ECMAScript 6, also known as ECMAScript 2015, is the upcoming version of the ECMAScript standard. This standard is targeting ratification in June 2015. ES6 is a significant update to the language, and the first update to the language since ES5 was standardized in 2009. Implementation of these features in major JavaScript engines is underway now.
See the draft ES6 standard for full specification of the ECMAScript 6 language.
