Looking for a templater script that outputs the date of the first day (monday) of the current week

What I’m trying to do

I am trying to find a way to quickly insert the date of the first day of the current week.
So I am looking for a templater script that outputs the date of the first day (monday) of the current week.

Things I have tried

The code that I can find is only a specific date on different formats.

Found it …


<%*
const today = moment();  // Get the current date using Moment.js
const firstDayOfWeek = today.startOf('isoWeek');  // Start of the current week (Monday)
tR += firstDayOfWeek.format('dddd, MMMM Do YYYY');  // Output the date in the desired format
%>
