/**
|
|
* 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).

* @since 4.0.0
|
|
* @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 }]
