How to add a week to a date and display it in the format?

Question

JavaScript

There is a date in this format "2020-11-30". You need to add a week to it and output in the same format "yyyy-mm-dd".

Answer 1

new Date(Date.parse('2020-11-30') + 7 * 24 * 60 * 60 * 1000)

UPD,
Or like this:

const d = new Date('2020-11-30')
d.setDate(d.getDate() + 7)
