Credo v1.4.0 Credo.Check.Refactor.AppendSingleItem View Source
This check has a base priority of low and works with any version of Elixir.
Explanation
When building up large lists, it is faster to prepend than append. Therefore: It is sometimes best to prepend to the list during iteration and call Enum.reverse/1 at the end, as it is quite fast.
Example:
list = list_so_far ++ [new_item]
# refactoring it like this can make the code faster:
list = [new_item] ++ list_so_far
# ...
Enum.reverse(list)Configuration parameters
There are no parameters for this check.
