Maybe its just me but the only things that I really like from this document are "Unicode", and "Tail Call", though some other things may be nice, the verbosity is killing me, how many new keywords, synatic constructs, and symbols are coming in with ECMA6? Though I have no say in the matter, for my 2 cents, I just wish they had used ECMA6 to remove things (mainly those listed here: http://johnkpaul.github.io/presentations/empirejs/javascript... and in Crockfords famous book http://archive.oreilly.com/pub/a/javascript/excerpts/javascr...) for instance.
