previousMonday

[YesUnO]

similiar to nextMonday. i ended up using soemthing from SO, because i didnt find this method in this library

import {
startOfMonth,
lastDayOfMonth,
nextSunday
isMonday
} from "date-fns";
...

function someFunction() {
...
var monthStart = startOfMonth(this.activeDate);
var prevMondayOfMonth = monthStart;

  if (!isMonday(monthStart)) prevMondayOfMonth.setDate(prevMondayOfMonth.getDate() - ((prevMondayOfMonth.getDay() + 6) % 7));

...
}

so i thought it might be usefull method in this library
