toMercator

Converts a WGS84 GeoJSON object into Mercator (EPSG:900913) projection

$3

* geojson ([GeoJSON][1] | [Position][2]) WGS84 GeoJSON object
* options [Object][3]? Optional parameters (optional, default {})

* options.mutate [boolean][4] allows GeoJSON input to be mutated (significant performance increase if true) (optional, default false)

$3

``javascript
var pt = turf.point([-71,41]);
var converted = turf.toMercator(pt);

//addToMap
var addToMap = [pt, converted];
`

Returns [GeoJSON][1] Projected GeoJSON
