 The `method` option is an [HTTP method](https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol#Request_methods). To retrieve data from the server without causing side-effects on the server, we need to use the `GET` method. The `url` is the address for the API endpoint. The `withCredentials: true` line indicates that we're using cookies (which is a requirement for the REM API).
 
-The `m.request` call returns a Promise that resolves to the data from the endpoint. By default, Mithril assumes a HTTP response body are in JSON format and automatically parses it into a Javascript object or array. The `.then` callback runs when the XHR request completes. In this case, the callback assigns the `reesult.data` array to `User.list`.

 Notice we also have a `return` statement in `loadList`. This is a general good practice when working with Promises, which allows us to register more callbacks to run after the completion of the XHR request.
