/** * 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. * * @static * @memberOf _ * @since 4.0.0 * @category 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 }] */var differenceBy = baseRest(function(array, values) {  var iteratee = last(values);  if (isArrayLikeObject(iteratee)) {    iteratee = undefined;  }  return isArrayLikeObject(array)    ? baseDifference(array, baseFlatten(values, 1, isArrayLikeObject, true), baseIteratee(iteratee, 2))    : [];});
