Unable to parse ISO-8601 date correctly

I'm attempting to parse a date returned to me from amazons Lex chatbot API. Some example return formats are ( From the API docs https://developer.amazon.com/docs/custom-skills/slot-type-reference.html#date )

“next week”: 2015-W49
“this weekend”: 2015-W48-WE
“this month”: 2015-11

My particular case is "2017-W47-WE".

I've tried parsing it in a couple of ways, with no luck

Vanilla

var newDate = new Date(date)   // Invalid date

MomentJS

moment(date)
moment(date, moment.ISO_8601).format('YYYY/MM/DD')
moment(date).format('YYYY-MM-DD')

None of which work, Does anyone have any idea how to correctly format this date? Thanks!

The -WE part is abit strange. Even if you can correctly parsed it I have no idea what should be returned. Since weekend includes two days (Saturday and Sunday) so should it be an array of moment objects?

Anyway, you can get weekend alternatively like so

var SAT_OF_WEEK_47 = moment("2017-W47-WE".replace("WE","6"), "YYYY-[W]WW-E").format()
var SUN_OF_WEEK_47 = moment("2017-W47-WE".replace("WE","7"), "YYYY-[W]WW-E").format()

I explicitly declared the format and use E 1..7 as ISO day of week. Let me know if this is what you are trying to achieve.
