Learn Basic String and Array Methods by Building a Music Player - Step 82

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 {
  }
});

Learn Basic String and Array Methods by Building a Music Player - Step 82

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!

Have you tried refreshing your browser? Close the tab completely perhaps and then try to open the challenge again.

Yes but nothing! the next exercise work!

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.
