What if this property exists?

Side note, this is very odd syntax - usually people don’t put extra spaces in there like that

You need to check if the property “tracks” exists.
If not, create!
After send the value.

This code does not fully cover the last instruction.

If prop is tracks and value isn’t an empty string, add the value to the end of the album’s tracks array. You need to create this array first if the album does not have a tracks property.

You only need to create the array first only if it doesn’t exist. You aren’t handling the case where the array already exists.

If something specific about my first post didn’t make sense, it would help if you are more specific in your reply. Otherwise it’s hard for us to make a better reply.
