//Client side

app.get('/trends', function(req, res){
  twitterProcessor.getTrends( function(error, trendData){
     res.render('trends.jade',{ locals: {
   	trends:trendData   // here's the data you pass to client
        }
     });		
  });
});

//Client side 
script(type='text/javascript')
    var data =!{JSON.stringify(trends)}

//And this is how it will see in the browser
<script type="text/javascript">
