Tell us what’s happening:

Hi

This is my code:
const playPreviousSong = () => {

if(userData?.currentSong === null){
return;
}else {
const currentSongIndex = getCurrentSongIndex();
}
};

The response I get when trying to pass my code is that I need to call the “playSong” function with “userData.songs[0].id” inside your “if” block"

Can anyone tell me where I am going wrong please?

Thanking you

Can you please talk a bit about how your code fulfills the instructions?

For example the first line:

const playPreviousSong = () => {

Can you please explain how this relates to one of the lines from the instructions?

I ask because I think it’s important to understand how you are coming up with this code and why it’s going wrong.
