Answer 1

If you are running into issues with the accepted answer above. I got it to work by creating a new Date and passing in the date parameter.

  private getTime(date?: Date) {
    return date != null ? new Date(date).getTime() : 0;
  }

  public sortByStartDate(array: myobj[]): myobj[] {
    return array.sort((a: myobj, b: myobj) => {
      return this.getTime(a.startDate) - this.getTime(b.startDate);
    });
  }
