How to check in json data for any column value is there array/collection present using Angular.js?

index.js

var app = angular.module('plunker', []);

app.controller('MainCtrl', function($scope) {

  $scope.data =[{"Id":1,"Title":"en-US","Description":"UnitedStates","MyValues":[{"demo":"dish","Id":100,"Value":"Save"}]},
{"Id":1,"Title":"en-UK","Description":"UK","MyValues":[{"demo":"Myvalu","Id":102,"Value":"Delete"}]}]
  $scope.cols = Object.keys($scope.data[0]);

  $scope.notSorted = function(obj){
    if (!obj) {
        return [];
    }
    return Object.keys(obj);
}  
});

I want to check in $scope.data is there any column value as array/collection in above code MyValues is a array/collection, I tried using angular.isArray(value) but it does not work.

You can use this check Array.isArray([1,2,3])

$scope.data.map(function(obj){
  return Object.keys(obj).filter(function(k){
       return Array.isArray(obj[k]);
    });
});

The code above will give you all the lists for each element in the Array of $scope.data ,, do you want a specific format ??
