Tell us what’s happening:

I don’t know where is the mistake

Your code so far

audio.addEventListener("ended", () => {
  const currentSongIndex = getCurrentSongIndex();
  const nextSongExists = currentSongIndex < userData?.songs.length - 1;
  
  if (nextSongExists) {
    const nextSong = userData?.songs[currentSongIndex + 1];
    playSong(nextSong.id);
  } else {
  }
});

Hey there! Welcome to the forums.

I don’t really think you need that if statement. Because the instructions only ask you to assign currentSongIndex to getCurrentSongIndex and check if the next song exists, and I think that’s where the issue is coming from (plus the if statement that is not needed). To check if a next song exists, you first want to make sure that userData exists, and that the next element is not undefined (that it exists for sure)

I hope this analogy helps.

I don’t know why I don’t find now the white space for coding and I don’t have the “hint” or “reset code” buttons!

I know this is a bit late, but if the instructions and reset button isn’t showing I bring the step up in another browser and it seems to work. Just in case anyone is having issues with that.

I also mistook it for creating if statement. then when I came to forum there is already one similar this existed.
