function objectToString(value) {
      return nativeObjectToString.call(value);
    }
This method is like `_.difference` except that it accepts `iteratee` which
is invoked for each element of `array` and `values` to generate the criterion
by which they're compared. The order and references of result values are
determined by the first array. The iteratee is invoked with one argument:
(value).

**Note:** Unlike `_.pullAllBy`, this method returns a new array.

@param {Array} array The array to inspect.
@param {...Array} [values] The values to exclude.
@param {Function} [iteratee=_.identity] The iteratee invoked per element.
@returns {Array} Returns the new array of filtered values.
@example

_.differenceBy([2.1, 1.2], [2.3, 3.4], Math.floor);
// => [1.2]

// The `_.property` iteratee shorthand.
_.differenceBy([{ 'x': 2 }, { 'x': 1 }], [{ 'x': 1 }], 'x');
// => [{ 'x': 2 }]
