In the previous lesson, we made an array filled on the right and left with empty strings. Let's now convert this array into a two-dimensional one. Let's make the following chunk function for this:
function chunk(arr, n) {
// n - a number of elements in subarray
}
You can use our function like this:
let res = chunk(normalize(arr, firstWeekDay, 6 - lastWeekDay), 7));
console.log(res);
Implement the described function chunk
and check its operation.
