 * Creates an array of elements split into groups the length of `size`.

 * @since 5.18.0
 * @category Array
 * @param array The array to process.
 * @param size The length of each chunk, default is 1
 * @returns Returns the new array of chunks.
 * @example
 *
 * ```js
 * chunk(['a', 'b', 'c', 'd'], 2)
 * // => [['a', 'b'], ['c', 'd']]
 *
 * chunk(['a', 'b', 'c', 'd'], 3)
 * // => [['a', 'b', 'c'], ['d']]
