chunkIntoN	array intermediate	Deepak Vishwakarma	https://github.com/deepakshrma	https://avatars2.githubusercontent.com/u/7682731?s=400	Implementation of "chunkIntoN" in typescript, javascript and deno.	https://www.positronx.io/wp-content/uploads/2018/11/positronx-banner-1152-1.jpg

Chunks an array into n smaller arrays.

Use Math.ceil() and Array.prototype.length to get the size of each chunk. Use Array.from() to create a new array of size n. Use Array.prototype.slice() to map each element of the new array to a chunk the length of size. If the original array can't be split evenly, the final chunk will contain the remaining elements.

const chunkIntoN = (arr, n) => {
  const size = Math.ceil(arr.length / n);
  return Array.from({ length: n }, (v, i) =>
    arr.slice(i * size, i * size + size)
  );
};

chunkIntoN([1, 2, 3, 4, 5, 6, 7], 4); // [[1,2], [3,4], [5,6], [7]]
