🕵️♀️ Task
When called on an ActiveRecord::Relation, .first returns the first record from the collection. If the collection is empty, .first returns nil.
You can optionally pass an Integer argument to .first. This will return n number of records from the ActiveRecord::Relation. If the collection is empty when you pass an argument, .first returns an empty Array.
Similar methods exist for second, third, fourth, fifth, forty_two, last, second_to_last, and third_to_last.
