在 javascript / moment.js 中获取每周的第一天

Question

Is there a way to get all the dates in the weeks or just the first day of each week and the last day of each week?

For example:

date = 2020-04-15

Then a code will get the date and take all the starting day of the week and the end day. The expected output is:

Week 1: 2020-04-06 to 2020-04-12

Week 2: 2020-04-13 to 2020-04-19

Week 3: 2020-04-20 to 2020-04-26

Week 4: 2020-04-27 to 2020-05-03

Answer 1

Get the first day of the current week (Sunday):

moment().subtract(moment().weekday(), 'days');

Get the last day of the current week (Satursday):

moment().add(6 - moment().weekday(), 'days');
