Creates a circular arc, of a circle of the given radius and center point, between bearing1 and bearing2;
0 bearing is North of center point, positive clockwise.

**Parameters**

-   `center` **[Feature](http://geojson.org/geojson-spec.html#feature-objects)<[Point](http://geojson.org/geojson-spec.html#point)>** center point
-   `radius` **[number](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number)** radius of the circle
-   `bearing1` **[number](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number)** angle, in decimal degrees, of the first radius of the arc
-   `bearing2` **[number](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number)** angle, in decimal degrees, of the second radius of the arc

**Examples**

```javascript
var center = turf.point([-75, 40]);
var radius = 5;
var bearing1 = 25;
var bearing2 = 47;

var arc = turf.lineArc(center, radius, bearing1, bearing2);

//addToMap
var addToMap = [center, arc]
```
