Improving Elixir Code Clarity with Enum Functions

In this article, the author highlights the common practice of using Enum.reduce in Elixir applications, arguing that while it is a powerful tool, it is not always the most readable option. He demonstrates through examples how other Enum functions like Enum.map, Enum.sum_by, and Enum.flat_map can be utilized for clearer code. Furthermore, he suggests that piping functions together can enhance readability and facilitate future refactoring. The author also addresses performance concerns, noting that for most use cases, the performance impact of using alternative functions is negligible. Additionally, he introduces a custom Credo check that can help developers identify instances of Enum.reduce that could be replaced with simpler alternatives, encouraging ongoing code improvement.
