     * This method is like `_.union` except that it accepts `iteratee` which is
     * invoked for each element of each `arrays` to generate the criterion by
     * which uniqueness is computed. Result values are chosen from the first
     * array in which the value occurs. The iteratee is invoked with one argument:
     * (value).
     *
     * @static
     * @memberOf _
     * @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 combined values.
     * @example
     *
     * _.unionBy([2.1], [1.2, 2.3], Math.floor);
     * // => [2.1, 1.2]
     *
     * // The `_.property` iteratee shorthand.
     * _.unionBy([{ 'x': 1 }], [{ 'x': 2 }, { 'x': 1 }], 'x');
     * // => [{ 'x': 1 }, { 'x': 2 }]
