Upvoted your comment so that everyone can see it. ES6 has template strings, destructuring assignment, Map and Set data structures (and more). While you're right and it is not NEEDED, this is something that dramatically improves on the weakest aspects of ECMASscript. Based on your comment, it feels like no addition is ever a good addition if you can express it with the building bricks you already have. With such a way of seeing things, we'd all be coding with assembly language, cause nothing really affects speed or memory consumption for the better.
