## destination

Takes a [Point][1] and calculates the location of a destination point given a distance in degrees, radians, miles, or kilometers; and bearing in degrees. This uses the [Haversine formula][2] to account for global curvature.

**Parameters**

-   `origin` **[Coord][3]** starting point
-   `distance` **[number][4]** distance from the origin point
-   `bearing` **[number][4]** ranging from -180 to 180
-   `options` **[Object][5]** Optional parameters (optional, default `{}`)
    -   `options.units` **[string][6]** miles, kilometers, degrees, or radians (optional, default `'kilometers'`)
    -   `options.properties` **[Object][5]** Translate properties to Point (optional, default `{}`)

**Examples**

```javascript
var point = turf.point([-75.343, 39.984]);
var distance = 50;
var bearing = 90;
var options = {units: 'miles'};

var destination = turf.destination(point, distance, bearing, options);

//addToMap
var addToMap = [point, destination]
destination.properties['marker-color'] = '#f00';
point.properties['marker-color'] = '#0f0';
```

Returns **[Feature][7]&lt;[Point][8]>** destination point
