DietJS: Respond with specific response code

Question

Going through all of the tutorials of DietJS here: Diet.js | Tutorials, I am not able to find a way to respond with a particular response code.

In the signals section, it is mentioned that we can use:

$.failure();

And we can put in more information about the failure through:

$.error("username", "missing");

But it responds with code 200 by default. There are no direct pointers towards setting up the desired response code.

After wasting a lot of time I figured out that you can actually do:

$.status(401, "Bad Request");

before you end the request with $.end(), $.failure() or any other alternatives.
