+## polygonSmooth
+
+Smooths a [Polygon][1] or [MultiPolygon][2]. Based on [Chaikin's algorithm][3].
+Warning: may create degenerate polygons.
+
+**Parameters**
+
+-   `inputPolys` **([FeatureCollection][4] \| [Feature][5]&lt;([Polygon][6] \| [MultiPolygon][7])>)** (Multi)Polygon(s) to smooth
+-   `options` **[Object][8]** Optional parameters (optional, default `{}`)
+    -   `options.iterations` **[string][9]** THe number of times to smooth the polygon. A higher value means a smoother polygon. (optional, default `1`)
+
+**Examples**
+
+```javascript
+var polygon = turf.polygon([[[11, 0], [22, 4], [31, 0], [31, 11], [21, 15], [11, 11], [11, 0]]]);
+
+var smoothed = turf.polygonSmooth(polygon, {iterations: 3})
+
+//addToMap
+var addToMap = [smoothed, polygon];
+```
+
+Returns **[FeatureCollection][4]&lt;[Polygon][6]>** FeatureCollection containing the smoothed polygon/poylgons
