Tell us what’s happening:
What do I need to change in my code to avoid errors? Can not understand.
This is problem:
After
updateRecords(collection, 5439, "tracks", "Take a Chance on Me")
,
tracks
should have
Take a Chance on Me
as the last element. After
updateRecords(collection, 1245, "tracks", "Addicted to Love")
,
tracks
should have
Addicted to Love
as the last element. After
updateRecords(collection, 2468, "tracks", "Free")
,
tracks
should have
1999
as the first element.
