+## combine
+
+Combines a [FeatureCollection][1] of [Point][2], [LineString][3], or [Polygon][4] features
+into [MultiPoint][5], [MultiLineString][6], or [MultiPolygon][7] features.
+
+**Parameters**
+
+-   `fc` **[FeatureCollection][8]&lt;([Point][9] \| [LineString][10] \| [Polygon][11])>** a FeatureCollection of any type
+
+**Examples**
+
+```javascript
+var fc = turf.featureCollection([
+  turf.point([19.026432, 47.49134]),
+  turf.point([19.074497, 47.509548])
+]);
+
+var combined = turf.combine(fc);
+
+//addToMap
+var addToMap = [combined]
+```
+
+Returns **[FeatureCollection][8]&lt;([MultiPoint][12] \| [MultiLineString][13] \| [MultiPolygon][14])>** a FeatureCollection of corresponding type to input
