Split array into chunks of size n

You want a function that takes an array and splits it into chunks of size n. Something like this:

chunkArray([2, 4, 6, 8, 10, 12, 14], 2)
// [[2, 4], [6, 8], [10, 12], [14]

If the array cannot be chunked into exact chunks of n, the remaining elements will form a separate chunk (e.g., [14] in the above example).

Here’s how in JavaScript:

function chunkArray<T>(arr: T[], chunkSize: number) {
  const chunkedArr = [];

  for(let index = 0; index < arr.length; index += chunkSize) {
    chunkedArr.push(arr.slice(index, index + chunkSize));
  }

  return chunkedArr;
}
