Unused parameter in function RVV-B0012

Unused parameters in functions or methods should be replaced with _ (underscore) or removed.

Functions or methods with unused parameters can be a symptom of unfinished refactoring or a bug. If an unused parameter is present, it should be named _ (underscore) to avoid raising this issue and better readability.

Bad practice

func abc(unused string) {
    fmt.Println("Not using any passed params.")
}

Recommended

func abc(_ string) {
    fmt.Println("Not using any passed params.")
}

func abc() {
    fmt.Println("Not using any passed params.")
}
