**Parameters**

-   `geojson` **([Feature](http://geojson.org/geojson-spec.html#feature-objects) \| [FeatureCollection](http://geojson.org/geojson-spec.html#feature-collection-objects))** input features

**Examples**

```javascript
var pt1 = turf.point([114.175329, 22.2524])
var pt2 = turf.point([114.170007, 22.267969])
var pt3 = turf.point([114.200649, 22.274641])
var pt4 = turf.point([114.200649, 22.274641])
var pt5 = turf.point([114.186744, 22.265745])
var features = turf.featureCollection([pt1, pt2, pt3, pt4, pt5])

var bbox = turf.bbox(features);

var bboxPolygon = turf.bboxPolygon(bbox);

//=bbox

//=bboxPolygon
```
