## Introduction
_Unused Parameter_ refers to methods with parameters that are unused in scope of the method.
Having unused parameters in a method is code smell because leaving dead code in
a method can never improve the method and it makes the code confusing to read.
## Example
Given:
```Ruby
class Klass
def unused_parameters(x,y,z)
puts x,y # but not z
end
end
```
Reek would emit the following warning:
```
[2]:UnusedParameters: Klass#unused_parameters has unused parameter 'z'
```
## Configuration
_Unused Parameter_ offers the [Basic Smell Options](Basic-Smell-Options.md).
