+/**
+* 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']]
