Tell us what’s happening:

Hello, I’ve been struggling with this one for a while. Here is my code:

The instructions are asking to set the values of currentTitle and currentArtist if they are truthy. I’ve set currentTitle/currentArtist equal to the results of the ternary operator,but receive an error/tip that says:

" You should use the ternary operator to set the textContent property of playingSong to currentTitle or "" . " Any help would be appreciated.

Your code so far

/* file: script.js */
// User Editable Region

  currentTitle = currentTitle ? playingSong.textContent : "";
  currentArtist = currentArtist ? songArtist.textContent : "";

// User Editable Region

This might be worded a bit strange, but what’s needed is modifying the playingSong.textContent and songArtist.textContent, with whatever will be returned in the ternary operation.

Hmm…I agree that your wording is a bit strange. Here is how i understand the ternary operation:

currentTitle ? playingSong.textContent : “”;
(condition) ? (return if true) : (return if false)

Is my understanding correct?

That’s correct - (condition) ? (return if true) : (return if false)

That means though, for currentTitle = currentTitle ? playingSong.textContent : "";:

  • If currentTitle is truthy, playingSong.textContent will be assigned to currentTitle.
  • If currentTitle is falsy, "" will be assigned to currentTitle.

Which is not the goal. It should be currentTitle or "" assigned to playingSong.textContent

Assignment is starting from left to right.

6

Assign ternary statement to textContent in both line of code.

7

Example

value.textContent = condition ? value : value;

Got it. Thank you for explaining it. The wording on the instructions really threw me off.

Thanks for your input here. Their wording on this one threw me for a loop as well for a while. This helped me to get the syntax right.
