    * This method is like `_.intersection` except that it accepts `iteratee`
    * which is invoked for each element of each `arrays` to generate the criterion
-   * by which uniqueness is computed. The iteratee is invoked with one argument: (value).
+   * by which they're compared. Result values are chosen from the first array.

    * @param {...Array} [arrays] The arrays to inspect.
    * @param {Function|Object|string} [iteratee=_.identity] The iteratee invoked per element.
