I would love an async/await feature. Though generators have been added, and they are currently optimization killers in V8: https://github.com/petkaantonov/blueb

  That's always the case for new language features. ES5 stuff was slow in the beginning and it took a while for v8 to catch up. This shouldn't be a reason for not using these new features. This article is also years old. While it seems to be updated recently I wonder how accurate it still is.
