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

Use padStart:

Date.prototype.yyyymmdd = function() {
    return [
        this.getFullYear(),
        (this.getMonth()+1).toString().padStart(2, '0'), // getMonth() is zero-based
        this.getDate().toString().padStart(2, '0')
    ].join('-');
};
