    Just add the days in the string array and iterate them backward by getting current date with new Date() this will return the index of current day

    const weekday = ["Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday"];

const d = new Date();
let day = weekday[d.getDay()];

var wanteddays = 8;
var temp = d.getDay()
while(wanteddays!=0){
    if (temp <0)
    temp = 6;
    console.log(weekday[temp]);
    temp = temp-1;
    wanteddays = wanteddays -1;
}

    function getDayName(date, len, local) {
  let newDate = new Date(date);
  let weekDays = [];

  Array(len).fill(1).forEach((subDay) => {
    newDate.setDate(newDate.getDate() - subDay);
    weekDays.push(newDate.toLocaleDateString(local, { weekday: 'long' }));
  })
  return weekDays;
}

    to use:

    getDayName(Date.now(), 7, 'en-EN') 
OR
getDayName('10/12/2022', 7, 'en-EN')

    Typescript:

    function getDayName(date: Date | string | number, len: number, local:string) {
  let newDate = new Date(date);
  let weekDays: string[] = [];

  Array(len).fill(1).forEach((subDay: number) => {
    newDate.setDate(newDate.getDate() - subDay);
    weekDays.push(newDate.toLocaleDateString(local, { weekday: 'long' }));
  })
  return weekDays;
}

    This should order an array to follow your wished output.

        var days = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];
    var currentDay = days[ (new Date()).getDay()]
    days =  days.reverse();
    var x = days.indexOf(currentDay)
    var daysLastSeven =  days.slice(x).concat(days.slice(0,x))

    console.log(daysLastSeven)
