  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
function numberOfMinutes(hours) {
  var seconds = 0;   // seconds is never used
  return hours * 60;
}


Compliant Solution
function numberOfMinutes(hours) {
  return hours * 60;
}
