angularjs - Update Mail Count With Angular -

i trying continuously keep updated count of unread messages. angular code have right doesn't replace current count puts new count next it. on , on again. not if using right method this. appreciated.

'use strict';  angular.module('chatapp') .controller('viewedctrl', function($scope, mail, $interval) {      var countloaded = function(count) {          $scope.count = count;     }      var handleerrors = function(response) {         console.error(response);     }      var getupdates = function() {     return mail.viewed().then(updatesloaded);     }      var updatesloaded = function(updates) {         $scope.count = $scope.count.concat(updates);     }      $interval(getupdates, 3000);          mail.count()         .then(countloaded)         .then(getupdates)         .catch(handleerrors);  }); 

i have {{count}} in view.

welcome stackoverflow! problem in updatesloaded function. using concat function append updates $scope.count variable.

for example:

// string var somestring = 'hello' somestring = somestring.concat(' world!') // 'hello world!'  // array var somearray = [1, 2] somearray = somearray.concat([3]) // [1, 2, 3] 

what want assign $scope.count whatever current count of unread mail.

so depending on value of updates is, work:

var updatesloaded = function (updates) {   $scope.count = updates )
