js array range

example.ts

// https://stackoverflow.com/a/33457557
const range = (start: number, end: number) =>
  new Array(end - start).fill(0).map((_, idx) => start + idx);

// https://stackoverflow.com/a/10050831
const range = (start: number, end: number) =>
  [...new Array(end - start).keys()].map((idx) => start + idx);

• keys() 같은 걸 활용할 수도 있다니…
