+## toMercator
+
+Converts a WGS84 GeoJSON object into Mercator (EPSG:900913) projection
+
+**Parameters**
+
+-   `geojson` **([GeoJSON][1] | Position)** WGS84 GeoJSON object
+-   `options` **[Object][2]?** Optional parameters
+    -   `options.mutate` **[boolean][3]** allows GeoJSON input to be mutated (significant performance increase if true) (optional, default `false`)
+
+**Examples**
+
+```javascript
+var pt = turf.point([-71,41]);
+var converted = turf.toMercator(pt);
+
+//addToMap
+var addToMap = [pt, converted];
+```
+
+Returns **[GeoJSON][1]** Projected GeoJSON
