Q: Did you mean to return the promise here? Or is this something you want to do
in parallel?

[mbrunson, 2016/10/06 17:45:01]

I didn't return it because I didn't care what order the information was logged
in. For consistency, I'll put a return here.

nit: Can you just do:

.then(logAdapterInfo)

?

[mbrunson, 2016/10/06 17:45:01]

Done.

       .then(function() { return adapter.getDevices(); })
       .then(function(response) { console.log(response.devices); })
       .catch(function(error) { console.error(error); });
   });
 })();
