Passo 9

Instruções

No seu objeto userData, crie uma propriedade songs e defina seu valor para o array allSongs. Então, para gerenciar as informações da música atual e acompanhar seu tempo de reprodução, crie as propriedades currentSong e songCurrentTime. Defina os valores para null e 0, respectivamente.

O que fazer:

Testes:

Seu objeto `userData` deve ter uma chave `songs` definida para o array `allSongs`.
Seu objeto `userData` deve ter uma chave `currentSong` definida como `null`.
Seu objeto `userData` deve ter uma chave `songCurrentTime` definida como `0`.
