Just a preference thing but sometimes people forget about this alternative:

Instead of typing: ```__dirname + '/' + 'orm' + '/' + model + '.js'```

You could do.. ```[__dirname, 'orm', model, 'js'].join(path.sep)```

This does two things:
1. Subjectively, it may look better to some
2. OS agnostic just in case if anyone, somewhere down the road, hates their life and wants to host an enterprise node app on a Windows machine ;)

The first point is far more important than the 2nd one. Either way, it's fine :)
