/**
* Splits an array into smaller arrays of a specified length.
*
* This function takes an input array and divides it into multiple smaller arrays,
* each of a specified length. If the input array cannot be evenly divided,
* the final sub-array will contain the remaining elements.
*
* @template T The type of elements in the array.
* @param arr - The array to be chunked into smaller arrays.
* @param size - The size of each smaller array. Must be a positive integer.
* @returns A two-dimensional array where each sub-array has a maximum length of `size`.
*
* @example
* // Splits an array of numbers into sub-arrays of length 2
* chunk([1, 2, 3, 4, 5], 2);
* // Returns: [[1, 2], [3, 4], [5]]
*
* @example
* // Splits an array of strings into sub-arrays of length 3
* chunk(['a', 'b', 'c', 'd', 'e', 'f', 'g'], 3);
* // Returns: [['a', 'b', 'c'], ['d', 'e', 'f'], ['g']]
