/**
 * Divides an array into smaller chunks of a specified size.
 *
 * @param {T[]} array - The array to be divided into chunks.
 * @param {number} size - The size of each chunk.
 * @returns {T[][]} An array of arrays, where each inner array is a chunk of the original array.
 *
 * @example
 * chunk([1, 2, 3, 4, 5], 2) // [[1, 2], [3, 4], [5]]
 * chunk(['a', 'b', 'c', 'd'], 3) // [['a', 'b', 'c'], ['d']]
