Answer

Since the number of days you’ll get will vary, it doesn’t make sense to create an array with a specific length up front.

I think I’d just use a do-while loop:

const MONDAY = 1; // The Date.prototype.getDay value for Monday

function selectWeek(date) {
    const dates = [new Date(+date)];
    let dt = new Date(+date);
    do {
        // Move back a day
        dt.setDate(dt.getDate() - 1);
        // Remember this day
        dates.unshift(new Date(+dt));
        // Stop looping when we've just pushed Monday
    } while (dt.getDay() !== MONDAY);
    return dates;
}

console.log(selectWeek(new Date()));

Since you said “last Monday,” that assumes that if you pass in a date that is a Monday, you should get eight days of dates (that day and the entire prior week).
