// Alter values below to test your code
updateRecords(2548, "tracks", "Addicted to Love");
all the tests pass except for the
After updateRecords(1245, “tracks”, “Addicted to Love”), tracks should have “Addicted to Love” as the last element.
tracks is an object/ array and the elements inside are strings and it is the last element. I am return collection right after so theres no overlapping with other code… I have no idea why its not passing the test. Please help! Thanks!
