Hello everyone, I am going to share the
AngularJs exception or error handling using  $exceptionHandler. The AngularJs $exceptionHandler  is use to catch and handle the exceptions or errors. The details as given below.
For live demo example http://embed.plnkr.co/x6bqJg/preview
The HTML Code-Sample
<div ng-app="exceptionApp" ng-controller="ExceptionCtrl"></div>
The AngularJs Code-Sample
var app =
angular.module('exceptionApp',
[]);
app.provider({
    $exceptionHandler: function () {
        var errorHandler = function (ex) {
            alert(ex);
            //console.log(ex);
        };
        this.$get = function () {
            return errorHandler;
        };
    }
});
app.controller('ExceptionCtrl', ["$scope", "$exceptionHandler", 
 function ($scope,
$exceptionHandler) {
    $scope.name = "Anil
Singh";
    //Throw error here using
handler as function.
    $exceptionHandler.handler('Throw error');
}]);
