+/**
+ * This method is like `_.pullAll` except that it accepts `iteratee` which is
+ * invoked for each element of `array` and `values` to to generate the criterion
+ * by which uniqueness is computed. The iteratee is invoked with one argument: (value).
+ *
+ * **Note:** Unlike `_.differenceBy`, this method mutates `array`.
+ *
+ * @static
+ * @memberOf _
+ * @category Array
+ * @param {Array} array The array to modify.
+ * @param {Array} values The values to remove.
+ * @param {Function|Object|string} [iteratee=_.identity] The iteratee invoked per element.
+ * @returns {Array} Returns `array`.
+ * @example
+ *
+ * var array = [{ 'x': 1 }, { 'x': 2 }, { 'x': 3 }, { 'x': 1 }];
+ *
+ * _.pullAllBy(array, [{ 'x': 1 }, { 'x': 3 }], 'x');
+ * console.log(array);
+ * // => [{ 'x': 2 }]
