Why is this an issue?
If a local variable is declared but not used, it is dead code and should be removed. Doing so will improve maintainability because developers will
not wonder what the variable is used for.
Noncompliant code example
public function numberOfMinutes(hours:int):int
{
var seconds:int = 0; // seconds is never used
return hours * 60;
}
Compliant solution
public function numberOfMinutes(hours:int):int
{
return hours * 60;
}
