How to check different properties available in routes ?

In event function, print the parameters : event, next and current

app.controller("studentController", function ($route, $http, $rootScope, $log) {
   $rootScope.$on("$locationChangeStart", function (event, next, current) {
       $log.debug("$locationChangeStart triggered...");
       $log.debug(event);
       $log.debug(next);
       $log.debug(current);
   })
 
   $rootScope.$on("$routeChangeStart", function (event, next, current) {
       $log.debug("$routeChangeStart triggered...");
       $log.debug(event);
       $log.debug(next);
       $log.debug(current);
   })
 
   var curr = this;
   curr.reloadData = function() {
      $route.reload();
   }
   $http.get("service/api/GetAllStudents").then(
     function(response) {
        curr.students = response.data;
     }
   )
});


The data in next and current object for $routeChangeStart and $locationChangeStart are different.

Output
$routeChangeStart triggered...
Object {name: "$routeChangeStart", targetScope: m, defaultPrevented: false, currentScope: m}
Object {params: Object, pathParams: Object, $$route: Object}
Object {params: Object, pathParams: Object, $$route: Object, loadedTemplateUrl: "Templates/students.html", locals: Object...}
$locationChangeStart triggered...
Object {name: "$locationChangeStart", targetScope: m, defaultPrevented: false, currentScope: m}
