/**
|
|
* 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 The iteratee invoked per element.
|
|
* @returns {Array} Returns the new array of filtered values.
|
|
* @see difference, union, unionBy, unionWith, without, xor, xorWith
|
|
* @example
|
|
*
|
|
* xorBy([2.1, 1.2], [2.3, 3.4], Math.floor)
|
|
* // => [1.2, 3.4]
