Responding to GET requests

Adding a simple GET request support is fairly simple, and you've already seen this before in the app we built.

    var data = { 
        name: 'Jason Krol', 
        website: 'http://kroltech.com' 
    }; 
    res.json(data); 
});

Add this new route after the /test route added previously:

router.get('/', (req, res)=>res.json(json));
