+## 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
