javascript what's the different between this two pieces of code?

I'm new to javascript and node. 1st:

app.get('/', function(req, res){
  articleProvider.findAll(function(error, docs){
      res.render('index.jade', { locals: {
        title: 'Blog',
        articles:docs
        }
      });
  });
});

2nd

app.get('/', function(req, res){
  articleProvider.findAll(function(error, docs){
      res.render('index.jade', {
        title: 'Blog',
        articles:docs
        }
      );
  });
});

1st code is from this tutorial http://howtonode.org/express-mongodb, but doesn't work. 2nd code did work, and i just don't know why? Other parts are exactly same.
