How I did things before on the server with PHP and the Laravel framework:

Route::get(‘user/{id}’, function($id) {
  $user = User::find($id);
  return Response::json($user->toArray());
});

And how I do the same thing now with node.js, Express and mongoose

app.route(‘/user/:id’).get(function(req, res) {
  User.findById(req.params.id).exec(function(err, user) {
    res.jsonp(user);
  });
});

Looking at this you might wonder what all the fuzz is about and why people get so emotional when talking about different programming languages.
