What’s happening here? You aren’t adding the name of the track to the new tracks array.

Thank you for your response so here the test says I should assign an empty array if the album does not have a tracks property. Please see below for more information.

Complete the function using the rules below to modify the object passed to the function.

  • Your function must always return the entire records object.
  • If value is an empty string, delete the given prop property from the album.
  • If prop isn’t tracks and value isn’t an empty string, assign the value to that album’s prop.
  • If prop is tracks and value isn’t an empty string, you need to update the album’s tracks array. First, if the album does not have a tracks property, assign it an empty array. Then add the value as the last item in the album’s tracks array.

Read this part again. It doesn’t actually say to only make an empty array and do nothing else. The instructions are more complicated.

First, if the album does not have a tracks property, assign it an empty array. Then add the value as the last item in the album’s tracks array.

Thank you for your response sir, it worked after adding the value to the empty tracks and fixing my assignment operator, i added two equal signs by mistake.

else if (records[id].hasOwnProperty(“tracks”) === false) {
records[id][prop] ==
