Basics

This check is disabled by default.

Learn how to enable it via .credo.exs.

This check has a base priority of normal and works with any version of Elixir.

Explanation

List.last/1 traverses the whole list. Prefer structuring code so the needed value is already available.

# bad
List.last(items)

# better when you control construction
[last | _] = Enum.reverse(items)
