## lineIntersect

Takes any LineString or Polygon GeoJSON and returns the intersecting point(s).

**Parameters**

-   `line1` **([Geometry][1] \| [FeatureCollection][2] \| [Feature][3]&lt;([LineString][4] \| [MultiLineString][5] \| [Polygon][6] \| [MultiPolygon][7])>)** any LineString or Polygon
-   `line2` **([Geometry][1] \| [FeatureCollection][2] \| [Feature][3]&lt;([LineString][4] \| [MultiLineString][5] \| [Polygon][6] \| [MultiPolygon][7])>)** any LineString or Polygon

**Examples**

```javascript
var line1 = turf.lineString([[126, -11], [129, -21]]);
var line2 = turf.lineString([[123, -18], [131, -14]]);
var intersects = turf.lineIntersect(line1, line2);

//addToMap
var addToMap = [line1, line2, intersects]
```

Returns **[FeatureCollection][2]&lt;[Point][8]>** point(s) that intersect both
