Hi there,

The syntax of a ternary operator is like this:

variable_name = condition ? value_if_true : value_if_false

What it does is:

check if condition is truthy. If so, set variable_name to value_if_true. Otherwise, set it to value_if_false.

What the instruction asked is:

check if currentTitle is truthy. If so, set playingSong.textContent to currentTitle. Otherwise, set it to an empty string.

So,
the condition here is currentTitle
the variable_name here is playingSong.textContent
…
and so on

The instruction said:

check if currentTitle is truthy. If so, set playingSong.textContent to currentTitle

So, value_if_true here is currentTitle

currentTitle is Value_if_true and condition

The key to the solution is not on how the ternary operator works. Read carefully, the form of the question can be confusing. Here you are assigning values to the ‘textContent’ attribute
