title: Difference between app.use and app.get in express.js
body: <p>I'm kind of new to express and node.js, and I can't figure out the difference between app.use and app.get. It seems like you can use both of them to send information. For example:</p>
  
  <pre><code>app.use('/',function(req, res,next) {
      res.send('Hello');
      next();
  });
  </code></pre>
  
  <p>seems to be the same as this:</p>
  
  <pre><code>app.get('/', function (req,res) {
     res.send('Hello');
  });
  </code></pre>
