Quick1: JS array of dates

I always disliked dates in JS, but as time goes by confidence grows. It does not help that I avoid reaching for external packages unless it is really necessary.

Today I needed to generate arrays of numbers that represent days between two dates.

// Outcome needed. Inputs 2020-10-28 and 2020-11-06
const labels = [28,29,30,13,1,2,3,4,5,6];

// Solution
export const getDatesBetweenDates = (
  startDate: string,
  endDate: string
): number[] => {
  const dates: number[] = [];
  const start = new Date(startDate);
  const end = new Date(endDate);
  while (start <= end) {
    dates.push(start.getDate());
    start.setDate(start.getDate() + 1);
  }
  return dates;
};

I have no idea why I thought that would be hard
