/**
 * Splits an array into chunks of a specified size.

 * @template T - The type of elements in the array
 * @param array - The array to chunk
 * @param size - The size of each chunk (must be positive)
 * @returns An array of chunks
 *
 * @example
 * ```ts
 * chunk([1, 2, 3, 4, 5], 2); // [[1, 2], [3, 4], [5]]
 * chunk(['a', 'b', 'c', 'd'], 3); // [['a', 'b', 'c'], ['d']]
 * chunk([1, 2, 3], 1); // [[1], [2], [3]]
