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 iteratee is invoked with one argument:
|
12 | * (value).

|
18 | * @param {...Array} [arrays] The arrays to inspect.
|
19 | * @param {Array|Function|Object|string} [iteratee=_.identity]
|
20 | * The iteratee invoked per element.
|
21 | * @returns {Array} Returns the new array of values.

|
24 | * _.xorBy([2.1, 1.2], [4.3, 2.4], Math.floor);

25 | * // => [1.2, 4.3]

27 | * // The `_.property` iteratee shorthand.
|
28 | * _.xorBy([{ 'x': 1 }], [{ 'x': 2 }, { 'x': 1 }], 'x');
