Credo v1.4.0 Credo.Check.Consistency.UnusedVariableNames View Source
This check has a base priority of high and works with any version of Elixir.
Explanation
Elixir allows us to use _ as a name for variables that are not meant to be
used. But it’s a common practice to give these variables meaningful names
anyway (_user instead of _), but some people prefer to name them all _.
A single style should be present in the same codebase.
Configuration parameters
There are no parameters for this check.
