Setup

function getRange(startFrom, until) {
  const result = [];
  for (let i = startFrom; i <= until; i++) {
    result.push(i);
  }
  return result;
}

function getRangeNew(startFrom, until) {
  const result = new Array(until - startFrom + 1);
  for (let i = startFrom; i <= until; i++) {
    result[i - startFrom] = i;
  }
  return result;
}

function arrayFrom(startFrom, until) {
	return Array.from({ length: until + 1 - startFrom }, (_, k) => k + startFrom);
}
