<!-- Generated by documentation.js. Update this documentation by updating the source code. -->

## bbox

Calculates the bounding box for any GeoJSON object, including FeatureCollection.
Uses geojson.bbox if available and options.recompute is not set.

### Parameters

*   `geojson` **[GeoJSON][1]** any GeoJSON object
*   `options` **[Object][2]** Optional parameters (optional, default `{}`)

    *   `options.recompute` **[boolean][3]?** Whether to ignore an existing bbox property on geojson

### Examples

```javascript
var line = turf.lineString([[-74, 40], [-78, 42], [-82, 35]]);
var bbox = turf.bbox(line);
var bboxPolygon = turf.bboxPolygon(bbox);

//addToMap
var addToMap = [line, bboxPolygon]
```

Returns **[BBox][4]** bbox extent in \[minX, minY, maxX, maxY] order
