Tell us what’s happening:

audio.addEventListener("ended", () => {
  const currentSongIndex = getCurrentSongIndex()
  const nextSongExists = (userData.songs.length - 1)
  if(userData.songs.length  > currentSongIndex){
    const nextSongExists = false
  }
  else{
    nextSongExists = true
  }
});

Your code so far

Learn Basic String and Array Methods by Building a Music Player - Step 87

hello guys am stuck up somewhere here on this step

2

Can you give more detail? what is the problem and/or hint?

3

its telling me that i need to modify the existing ended event listener and its content.

4

Hi. You need to use ternary operator.

5

hey am still stuck on how i can make it out

6

I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

7

syntax error:
const variables can’t be redeclared or reassigned

8 
audio.addEventListener("ended", () => {
  const currentSongIndex = getCurrentSongIndex()
  if(userData.songs.length > currentSongIndex? 'true':'false'){
     nextSongExists = false
  }
  else{
    nextSongExists = true
  }
});

i aint using const but still telling me to modify the ended click event

You need to learn more about the ternary operator and how to use it properly. Example:

const someVariable = x > y ? true : false;
10

You should not modify the existing ended event listener and its content.

it seems you changed something you should not have changed

for this your nextSongExists will always be false. The requirement is to have a const variable with the appropriate boolean value, you get that assigning a comparison to the variable, so remove your if statement

hey @hiekamara1

It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.
