v-for with child object-CodePudding

Have been trying for a while to make a v-for list on the child elements {song: "xxx"} object in songs?

export const data = [
{id: "1", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "2", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "3", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "4", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "5", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "6", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "7", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "8", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "9", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "10", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "11", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "12", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "13", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "14", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "15", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "16", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "17", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},

This is my try, it does not work! (data is the variable where the parent object is stored.

 <div  v-for="item in data.songs.song" :key="item.id">
     {{ item.songs }}
   </div>

Thank you!

Try like following snippet:

const app = Vue.createApp({
  data() {
    return {
      albums: [
{id: "1", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "2", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "3", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
{id: "4", albumname: "xx", artist: "xxxx", dateadded: "xxxx", route: "xxxx", songs: [{ song : 'check2.1' }, { song : 'check2.2' }]},
