+## lineToPolygon
+
+Converts (Multi)LineString(s) to Polygon(s).
+
+**Parameters**
+
+-   `lines` **([FeatureCollection][1] \| [Feature][2]&lt;([LineString][3] \| [MultiLineString][4])>)** Features to convert
+-   `options` **[Object][5]** Optional parameters (optional, default `{}`)
+    -   `options.properties` **[Object][5]** translates GeoJSON properties to Feature (optional, default `{}`)
+    -   `options.autoComplete` **[boolean][6]** auto complete linestrings (matches first & last coordinates) (optional, default `true`)
+    -   `options.orderCoords` **[boolean][6]** sorts linestrings to place outer ring at the first position of the coordinates (optional, default `true`)
+
+**Examples**
+
+```javascript
+var line = turf.lineString([[125, -30], [145, -30], [145, -20], [125, -20], [125, -30]]);
+
+var polygon = turf.lineToPolygon(line);
+
+//addToMap
+var addToMap = [polygon];
+```
+
+Returns **[Feature][2]&lt;([Polygon][7] \| [MultiPolygon][8])>** converted to Polygons
