 /**
- * Takes two {@link Polygon} features and finds their intersection.
+ * Takes two {@link Polygon|polygons} and finds their intersection. If they share a border, returns the border; if they don't intersect, returns undefined.
  *
  * @module turf/intersect
  * @category transformation
- * @param {Polygon} poly1 the first Polygon
- * @param {Polygon} poly2 the second Polygon
- * @return {Polygon} a Polygon feature representing the area where `poly1` and `poly2` overlap
+ * @param {Feature<Polygon>} poly1 the first polygon
+ * @param {Feature<Polygon>} poly2 the second polygon
+ * @return {(Feature<Polygon>|undefined|Feature<MultiLineString>)} if `poly1` and `poly2` overlap, returns a Polygon feature representing the area they overlap; if `poly1` and `poly2` do not overlap, returns `undefined`; if `poly1` and `poly2` share a border, a MultiLineString of the locations where their borders are shared
