/** |
|
* This method is like `_.xor` except that it accepts `iteratee` which is |
|
* invoked for each element of each `arrays` to generate the criterion by |
|
* which by which they're compared. The order of result values is determined |
|
* by the order they occur in the arrays. The iteratee is invoked with one |
|
* argument: (value). |

|
* @category Array |
|
* @param {...Array} [arrays] The arrays to inspect. |
|
* @param {Function} [iteratee=_.identity] The iteratee invoked per element. |
|
* @returns {Array} Returns the new array of filtered values. |
|
* @example |
|
* |
|
* _.xorBy([2.1, 1.2], [2.3, 3.4], Math.floor); |
|
* // => [1.2, 3.4] |
|
* |
|
* // The `_.property` iteratee shorthand. |
|
* _.xorBy([{ 'x': 1 }], [{ 'x': 2 }, { 'x': 1 }], 'x'); |
|
* // => [{ 'x': 2 }] |
