+### sendStatus(code)
+The `sendStatus` method sets the status code and returns its string representation as the response body. The `sendStatus()` method accepts a single integer argument.
+
+```javascript
+res.sendStatus(200) // equivalent to res.status(200).send('OK')
+res.sendStatus(304) // equivalent to res.status(304).send('Not Modified')
+res.sendStatus(403) // equivalent to res.status(403).send('Forbidden')
+```
+
+**NOTE:** If an unsupported status code is send, it will return 'Unknown' as the body.

 ### header(key, value [,append])
 The `header` method allows for you to set additional headers to return to the client. By default, just the `content-type` header is sent with `application/json` as the value. Headers can be added or overwritten by calling the `header()` method with two string arguments. The first is the name of the header and then second is the value. You can utilize multi-value headers by specifying an array with multiple values as the `value`, or you can use an optional third boolean parameter and append multiple headers.
