This is My Console. Look this is the object containing Data and Method details(AFTER A220)

While I Trying Convert the object into an array this method details also got convert into separate array.

This is the Out Put (Look it Converts that things into an array)

    <script>
    
    var app = angular.module("myApp", ['restangular']);
        app.controller("myCtrl", function($scope,Restangular) {
            $scope.clickme=function(){
        Restangular.setBaseUrl('http://localhost:8080/StrutsREST/api');
        Restangular.all('interfaces').doGET().then(function(data) {
        console.log(data);
            let arr=Object.entries(data);
        console.log(arr);
            }) 
        }
        });
</script>
