I have the following loop that checks if the date is holiday and thereon, fills up the Date[].

if (
          this._dateHelperService.isBusinessDay(temporalDate) &&
          !this._dateHelperService.isHoliday(temporalDate)
        ) {
          mNumberOfDays += 1;
          console.log(temporalDate.toDateString());
          console.log('entre')
          let tmpDate: Date[] = [...result.datesToPaint, temporalDate];
          result.datesToPaint = tmpDate;
          console.table(result.datesToPaint)
          // console.log(mNumberOfDays);
        }
        // re creating the date using a helper service
        if (mNumberOfDays !== numberOfDays) {
           temporalDate = 
           this._dateHelperService.addDays(temporalDate,1);
        }

        // helper service:
        addDays(date: Date, days: number): Date {
            date.setDate(date.getDate() + days);
            return date;
        }

The issue is that every time I assign a new element all the list data gets modified to the latest element. Here is a snapshot of the issue:

I'm aware this may be related to the pointer I have on the global list I created at the start of the method for result.datesToPaint. I tried using the spread operator and assigning the date to another date temporally. Still not working. Thanks for the help!
