I thought about this the other day and it seems to me, if you were to use 
something like AMD (require.js), your container would be a simple 
configuration. This line is basically asking a container to provide a data 
provider with an id.

define(['dataProvider'], function(provider) {
});

Switching out providers is fairly easy as your container would define a 
mock provider in testing and the real one in live mode. This isn't exactly 
the heavy DI that's common in C#/Java. I've learned to accept simplicity is 
a good thing.
