Moment.JS - Get date from week number

Question

I don't see this in the documentation of moment.js. Maybe I'm skipping over it but I want to convert a week number in a year to a date format.

for example

week: number = 13 
year: number = 2017
date: date = // get date format for the first day of that week

I'm using moment.js, but I can't find what I want in the documentation. Is this possible to do? I've found some answers for plain javascript, but since I'm already using moment.js, I figured there might be an easy way to do this

Answer 1

Yes, it's possible:

var date = moment('2017').add(13, 'weeks');

Note that moment('2017') returns January 1st of 2017.
