## cleanCoords

Removes redundant coordinates from any GeoJSON Geometry.

### Parameters

*   `geojson` **([Geometry][1] | [Feature][2])** Feature or Geometry
*   `options` **[Object][3]** Optional parameters (optional, default `{}`)

    *   `options.mutate` **[boolean][4]** allows GeoJSON input to be mutated (optional, default `false`)

### Examples

```javascript
var line = turf.lineString([[0, 0], [0, 2], [0, 5], [0, 8], [0, 8], [0, 10]]);
var multiPoint = turf.multiPoint([[0, 0], [0, 0], [2, 2]]);

turf.cleanCoords(line).geometry.coordinates;
//= [[0, 0], [0, 10]]

turf.cleanCoords(multiPoint).geometry.coordinates;
//= [[0, 0], [2, 2]]
```

Returns **([Geometry][1] | [Feature][2])** the cleaned input Feature/Geometry
