• seq.sorted()

• seq.sorted(by:)

• seq.sorted(_:) - sort by keypaths with ascending/descending orders

⭐️ 重點

the sorted(by:) function is actually 2 different functions.

• one requires Comparable and uses < internally.

• the other lets you specify the sorting logic directly (Comparable conformance not required).

... this convenience sorting by keyPath would still require 2 functions.

👉 Reference default comparison function as a function parameter
