Storing LocalStorage configuration objects within an array in an Ionic list

I am currently experimenting with LocalStorage in order to store an array containing objects. The issue I'm facing is that the code snippet below is displaying an object in the console instead of returning an array. Due to this, my ion-list is unable to read it. Is there a workaround for this situation, allowing me to retrieve the value as an array with all my objects included? Each object within the array holds various properties like ID, title, etc. My goal is to store multiple presentations in the array and then access and display them individually in the ion list.

Manager.js

 playlistService.addPlaylistAll = function (presentation) {

      console.log("setting item");
        var playlistarraytest = [];
      playlistarraytest.push(presentation);
      console.log("array first!! ", playlistarraytest);
      localStorage.setItem('playlisttest', playlistarraytest);
        playlistService.refresh();
      var test = localStorage.getItem('playlisttest');
       console.log(test);
}

Playlist.html

 <ion-list ng-repeat="presentation in dayOne = (playlist | filter: { day: 1 } | orderBy: 'start_date')">

Storing data structures directly in LocalStorage is not supported. LocalStorage has the capability to store only strings. Therefore, the following method should be used:

let jsonData = JSON.stringify(exampleArray);
localStorage.setItem('exampleData', jsonData);

To retrieve the stored data, you can use the following technique:

var data = localStorage.getItem('exampleData');
let newArray = JSON.parse(data);
console.log(newArray);
