## booleanOverlap

Compares two geometries of the same dimension and returns true if their intersection set results in a geometry
different from both but of the same dimension. It applies to Polygon/Polygon, LineString/LineString,
Multipoint/Multipoint, MultiLineString/MultiLineString and MultiPolygon/MultiPolygon.

**Parameters**

-   `feature1` **([Geometry][1] \| [Feature][2]&lt;([LineString][3] \| [MultiLineString][4] \| [Polygon][5] \| [MultiPolygon][6])>)** input
-   `feature2` **([Geometry][1] \| [Feature][2]&lt;([LineString][3] \| [MultiLineString][4] \| [Polygon][5] \| [MultiPolygon][6])>)** input

**Examples**

```javascript
var poly1 = turf.polygon([[[0,0],[0,5],[5,5],[5,0],[0,0]]]);
var poly2 = turf.polygon([[[1,1],[1,6],[6,6],[6,1],[1,1]]]);
var poly3 = turf.polygon([[[10,10],[10,15],[15,15],[15,10],[10,10]]]);

turf.booleanOverlap(poly1, poly2)
//=true
turf.booleanOverlap(poly2, poly3)
//=false
```

Returns **[boolean][7]** true/false
