+## bboxClip
+
+Takes a [Feature][1] and a bbox and clips the feature to the bbox using [lineclip][2].
+May result in degenerate edges when clipping Polygons.
+
+**Parameters**
+
+-   `feature` **[Feature][3]&lt;([LineString][4] \| [MultiLineString][5] \| [Polygon][6] \| [MultiPolygon][7])>** feature to clip to the bbox
+-   `bbox` **[BBox][8]** extent in [minX, minY, maxX, maxY] order
+
+**Examples**
+
+```javascript
+var bbox = [0, 0, 10, 10];
+var poly = turf.polygon([[[2, 2], [8, 4], [12, 8], [3, 7], [2, 2]]]);
+
+var clipped = turf.bboxClip(poly, bbox);
+
+//addToMap
+var addToMap = [bbox, poly, clipped]
+```
+
+Returns **[Feature][3]&lt;([LineString][4] \| [MultiLineString][5] \| [Polygon][6] \| [MultiPolygon][7])>** clipped Feature
