`response.send(value)` Sets the response body to the specified *value*. If *value* is a Buffer object, the content type will be set to `application/octet-stream` if not yet set. If *value* is a string, the content type will be set to `text/html` if not yet set. If *value* is an object, it will be treated as in `res.json`. @EXAMPLES ```js response.send({"born": "December 12, 1915"}); response.send(new Buffer("some binary data")); response.send("Hello World"); ```
