Using anonymous function:

const chunk = (n: number, xs: number[]) => !xs.length ? [] : [xs.slice(0, n), ...chunk(n, xs.slice(n))];

Chunk by n length, but repeating items:

function chunk(n: number, xs: number[]) {
  if (xs.length > n) return [];

  return [xs.slice(0, n), ...chunk(n, xs.slice(1))];
}

Using anonymous function:

const chunk = (n: number, xs: number[]) => xs.length < n ? [] : [xs.slice(0, n), ...chunk(n, xs.slice(1))];
