Problem:
How to get the first day of the week from current date?
Get the Monday of the Current week using JavaScript.

Solution:
Using the getDay() method of Date objects, you can know the number of day of the week (being 0=Sunday, 1=Monday, etc).

You can then subtract that number of days plus one, for example:

function getMondayOfCurrentWeek() {
   const today = new Date();
   const first = today.getDate() - today.getDay() + 1;

   const monday = new Date(today.setDate(first));
   return monday;
}

console.log(getMondayOfCurrentWeek());
