 /**
  * 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.
- * @returns {Array} Returns the new array of shared values.
+ * @returns {Array} Returns the new array of intersecting values.

  * _.intersectionBy([2.1, 1.2], [4.3, 2.4], Math.floor);
