/**
 * Creates an array of unique values that is the symmetric difference of the given arrays after applying the iteratee function to each element.
 *
 * This function takes multiple arrays and an iteratee function (or property key) to
 * compare the elements after transforming them. It returns a new array containing elements that are present
 * in exactly one of the arrays after applying the iteratee to each element.
 *
 * @template T1, T2
 * @param {ArrayLike<T1> | null | undefined} array - The first array to compare.
 * @param {ArrayLike<T2>} values - The second array to compare.
 * @param {(value: T1 | T2) => unknown | string} iteratee - The iteratee invoked on each element
 *  for comparison. It can also be a property key to compare based on that property.
 * @returns {Array<T1 | T2>} A new array containing elements that are present in exactly one of the arrays
 *  after applying the iteratee.
 *
 * @example
 * const array1 = [{ x: 1 }, { x: 2 }, { x: 3 }];
 * const array2 = [{ x: 2 }, { x: 3 }, { x: 4 }];
 * const result = xorBy(array1, array2, 'x');
 * // result will be [{ x: 1 }, { x: 4 }] since these elements are unique to their respective arrays.
 *

 * const array2 = [{ x: 2 }, { x: 3 }, { x: 4 }];
 * const result = xorBy(array1, array2, value => value.x);
 * // result will be [{ x: 1 }, { x: 4 }] since these elements are unique to their respective arrays.
