like python range

range.js

const range = (from, to, step) => {
  if (from === undefined) return [];
  if (to === undefined) return [...Array(from).keys()];
  if (step === undefined)
    return [...Array(to - from).keys()].map(x => x + from);
  return [...Array(Math.ceil((to - from) / step)).keys()].map(
    x => x * step + from
  );
};
export default range;
