9 * This method is like `_.xor` except that it accepts `iteratee` which is
10 * invoked for each element of each `arrays` to generate the criterion by
11 * which by which they're compared. The order of result values is determined
12 * by the order they occur in the arrays. The iteratee is invoked with one
13 * argument: (value).
14 *
15 * @static
16 * @memberOf _
17 * @since 4.0.0
18 * @category Array
19 * @param {...Array} [arrays] The arrays to inspect.
20 * @param {Function} [iteratee=_.identity] The iteratee invoked per element.
21 * @returns {Array} Returns the new array of filtered values.
22 * @example
23 *
24 * _.xorBy([2.1, 1.2], [2.3, 3.4], Math.floor);
25 * // => [1.2, 3.4]
26 *
27 * // The `_.property` iteratee shorthand.
28 * _.xorBy([{ 'x': 1 }], [{ 'x': 2 }, { 'x': 1 }], 'x');
29 * // => [{ 'x': 2 }]
