 5   * This method is like `_.pullAll` except that it accepts `iteratee` which is
 6   * invoked for each element of `array` and `values` to generate the criterion
 7   * by which they're compared. The iteratee is invoked with one argument: (value).
 8   *
 9   * **Note:** Unlike `_.differenceBy`, this method mutates `array`.

14   * @category Array
15   * @param {Array} array The array to modify.
16   * @param {Array} values The values to remove.
17   * @param {Function} [iteratee=_.identity] The iteratee invoked per element.
18   * @returns {Array} Returns `array`.
19   * @example
20   *
21   * var array = [{ 'x': 1 }, { 'x': 2 }, { 'x': 3 }, { 'x': 1 }];
22   *
23   * _.pullAllBy(array, [{ 'x': 1 }, { 'x': 3 }], 'x');
24   * console.log(array);
25   * // => [{ 'x': 2 }]
