# @turf/midpoint

# midpoint

Takes two [points](http://geojson.org/geojson-spec.html#point) and returns a point midway between them.
The midpoint is calculated geodesically, meaning the curvature of the earth is taken into account.

**Parameters**

-   `point1` **([Geometry](http://geojson.org/geojson-spec.html#geometry) \| [Feature](http://geojson.org/geojson-spec.html#feature-objects)<[Point](http://geojson.org/geojson-spec.html#point)> | [Array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array)<[number](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number)>)** first point
-   `point2` **([Geometry](http://geojson.org/geojson-spec.html#geometry) \| [Feature](http://geojson.org/geojson-spec.html#feature-objects)<[Point](http://geojson.org/geojson-spec.html#point)> | [Array](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array)<[number](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number)>)** second point

**Examples**

```javascript
var point1 = turf.point([144.834823, -37.771257]);
var point2 = turf.point([145.14244, -37.830937]);

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

//addToMap
var addToMap = [point1, point2, midpoint];
midpoint.properties['marker-color'] = '#f00';
```

Returns **[Feature](http://geojson.org/geojson-spec.html#feature-objects)<[Point](http://geojson.org/geojson-spec.html#point)>** a point midway between `pt1` and `pt2`
