const chunk = (arr, size) => Array.from({ length: Math.ceil(arr.length / size) }, (v, i) => arr.slice(i * size, i * size + size) ); chunk([1, 2, 3, 4, 5], 2); // [[1,2],[3,4],[5]]

Chunks an array into smaller arrays of a specified size.

Use Array.from() to create a new array, that fits the number of chunks that will be produced. 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.

An example:

chunk([1, 2, 3, 4, 5], 2); // [[1,2],[3,4],[5]]
