Using Moment.js to find a specific day of the current week's date

Question

this week's sunday

moment().startOf('week')

this week's monday

moment().startOf('isoweek')

this week's saturday

moment().endOf('week')

difference between the current day to sunday

moment().diff(moment().startOf('week'),'days')

this week's wedesday

moment().startOf('week').add('days', 3)

Maybe a little late to the party, but here's the proper way to do this, as in the documentation.

moment().day(1); // Monday in the current week

Also if in your locale it happens that the week starts with Monday and you wish to get a locally aware result, you can use moment().weekday(0). Here's the documentation for the moment().weekday(dayNumber) method.

It's not longer possible to use just a string (e. g. 'isoweek'), we need to use it like this:

import * as moment from 'moment';
import { unitOfTime } from 'moment';

moment().startOf('isoweek' as unitOfTime.StartOf);
