Challenge: Basic JavaScript - Record Collection

Link to the challenge:

" 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 aren’t implementing this requirement correctly. You need to create the tracks array if it doesn’t exist and then you need to add value to that array.
