Get String in YYYYMMDD format from JS date object?

Question

I\'m trying to use JS to turn a date object into a string in YYYYMMDD format. Is there an easier way than concatenating Date.getYear()

Answer 1

new Date('Jun 5 2016').
  toLocaleString('en-us', {year: 'numeric', month: '2-digit', day: '2-digit'}).
  replace(/(\d+)\/(\d+)\/(\d+)/, '$3-$1-$2');

// => '2016-06-05'
