There isn't a complete implementation, no. To some extent because parts of the spec aren't yet stable enough, but mostly because implementing all new features is a huge amount of work. Substantial parts of the spec are, however, implemented in various engines. A good overview of the current state can be seen here: http://kangax.github.io/es5-compat-table/es6/ Additionally, there are a few transpilers that transform ES6 code (again, not with all features supported) to ES5 as supported in pretty much all browsers nowadays. Traceur, one of those, is in the table I linked to above.
