Basics

This check is enabled by default.
Learn how to disable it via .credo.exs.

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

Boolean operations with identical values on the left and right side are most probably a logical fallacy or a copy-and-paste error.

Examples:

x && x
x || x
x and x
x or x

Each of these cases behaves the same as if you were just writing x.

There are no specific parameters for this check.

Like with all checks, general params can be applied.

Parameters can be configured via the .credo.exs config file.
