10 * Creates an array of elements split into groups the length of `size`.
11 * If `array` can't be split evenly, the final chunk will be the remaining
12 * elements.
13 *
14 * @static
15 * @memberOf _
16 * @since 3.0.0
17 * @category Array
18 * @param {Array} array The array to process.
19 * @param {number} [size=1] The length of each chunk
20 * @param- {Object} [guard] Enables use as an iteratee for methods like `_.map`.
21 * @returns {Array} Returns the new array of chunks.
22 * @example
23 *
24 * _.chunk(['a', 'b', 'c', 'd'], 2);
25 * // => [['a', 'b'], ['c', 'd']]
26 *
27 * _.chunk(['a', 'b', 'c', 'd'], 3);
28 * // => [['a', 'b', 'c'], ['d']]
