+## buffer
+
+Calculates a buffer for input features for a given radius. Units supported are miles, kilometers, and degrees.
+
+When using a negative radius, the resulting geometry may be invalid if
+it's too small compared to the radius magnitude. If the input is a
+FeatureCollection, only valid members will be returned in the output
+FeatureCollection - i.e., the output collection may have fewer members than
+the input, or even be empty.
+
+**Parameters**
+
+-   `geojson` **([FeatureCollection][1] \| [Geometry][2] \| [Feature][3]&lt;any>)** input to be buffered
+-   `radius` **[number][4]** distance to draw the buffer (negative values are allowed)
+-   `options` **[Object][5]** Optional parameters (optional, default `{}`)
+    -   `options.units` **[string][6]** any of the options supported by turf units (optional, default `"kilometers"`)
+    -   `options.steps` **[number][4]** number of steps (optional, default `8`)
+
+**Examples**
+
+```javascript
+var point = turf.point([-90.548630, 14.616599]);
+var buffered = turf.buffer(point, 500, {units: 'miles'});
+
+//addToMap
+var addToMap = [point, buffered]
+```
+
+Returns **([FeatureCollection][1] \| [Feature][3]&lt;([Polygon][7] \| [MultiPolygon][8])> | [undefined][9])** buffered features
