+
+#### reverse( x )
+
+Reverses an array in-place.
+
+```javascript
+var x = [ 1, 2, 3, 4, 5, 6 ];
+
+var out = reverse( x );
+// returns [ 6, 5, 4, 3, 2, 1 ]

+
+## Notes
+
+-   If provided an array-like object having a `reverse` method, the function defers execution to that method and assumes that the method API has the following signature:
+
+    ```text
+    x.reverse()
+    ```
+
+-   If provided an array-like object without a `reverse` method, the function manually reverses elements and mutates the input array.
