What is the best way to access a specific value within an array that contains a mix of objects and arrays

Currently, I am attempting to extract particular values from an array that is nested within another array. Specifically, I am utilizing the Spotify Web API to retrieve the track names from a playlist.

Here is an illustration of how the nested array is structured:

Object
tracks: Object
        items: Array [4]
               0: Object
                 track: Object
                        name
               1: Object
                 track: Object
                        name
               [...]

Within my Ionic/Angular application, I am utilizing the angular-spotify module. I tried to extract the track names using the following code:

Spotify
.getPlaylist('User-ID', 'Playlist-ID')
.then(function (data) {
  console.log(data); 
  arrayLength = data.tracks.items.length;
  for (i = 0; i < arrayLength; i++) {
    alert(track[i]);
  }
});

However, the console is indicating that the name is not defined. Can you please assist me in identifying where I may have made a mistake?

Answer №1

The track variable needs to be defined before using it in the loop. You can define it outside of the loop.

let track = data.tracks.items[i];
