# bearing

Takes two [points](http://geojson.org/geojson-spec.html#point) and finds the geographic bearing between them,
i.e. the angle measured in degrees from the north line (0 degrees)

**Parameters**

-   `start` **[Feature](http://geojson.org/geojson-spec.html#feature-objects)<[Point](http://geojson.org/geojson-spec.html#point)>** starting Point
-   `end` **[Feature](http://geojson.org/geojson-spec.html#feature-objects)<[Point](http://geojson.org/geojson-spec.html#point)>** ending Point
-   `final` **\[[boolean](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Boolean)]** calculates the final bearing if true (optional, default `false`)

**Examples**

```javascript
var point1 = {
  "type": "Feature",
  "properties": {},
  "geometry": {
    "type": "Point",
    "coordinates": [-75.343, 39.984]
  }
};
var point2 = {
  "type": "Feature",
  "properties": {},
  "geometry": {
    "type": "Point",
    "coordinates": [-75.534, 39.123]
  }
};

var bearing = turf.bearing(point1, point2);

//addToMap
var addToMap = [point1, point2]
point1.properties['marker-color'] = '#f00'
point2.properties['marker-color'] = '#0f0'
point1.properties.bearing = bearing
```

Returns **[number](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number)** bearing in decimal degrees, between -180 and 180 degrees (positive clockwise)
