+## mask
+
+Takes any type of [polygon][1] and an optional mask and returns a [polygon][1] exterior ring with holes.
+
+**Parameters**
+
+- `polygon` **([FeatureCollection][2] \| [Feature][3]&lt;([Polygon][4] \| [MultiPolygon][5])>)** GeoJSON Polygon used as interior rings or holes.
+- `mask` **[Feature][3]&lt;[Polygon][4]>?** GeoJSON Polygon used as the exterior ring (if undefined, the world extent is used)
+
+**Examples**
+
+```javascript
+var polygon = turf.polygon([
+  [
+    [112, -21],
+    [116, -36],
+    [146, -39],
+    [153, -24],
+    [133, -10],
+    [112, -21],
+  ],
+]);
+var mask = turf.polygon([
+  [
+    [90, -55],
+    [170, -55],
+    [170, 10],
+    [90, 10],
+    [90, -55],
+  ],
+]);
+
+var masked = turf.mask(polygon, mask);
+
+//addToMap
+var addToMap = [masked];
+```
+
+Returns **[Feature][3]&lt;[Polygon][4]>** Masked Polygon (exterior ring with holes).
