Jammming question wording

Could someone give me some clarification on question 63 of the Jamming app?

In App.js create a method called savePlaylist with the following functionality:

  • Generates an array of uri values called trackURIs from the playlistTracks property.
  • In a later step, you will pass the trackURIs array and playlistName to a method that will save the user’s playlist to their account.

What exactly are they asking me to do here? I feel like the wording is a little odd.
