## 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

## toWgs84

-   `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([-7903683.846322424, 5012341.663847514]);
var converted = turf.toWgs84(pt);

//addToMap
