        Why is this an issue?

        More Info

        Using the same value on both sides of a binary operator is a code defect. In the case of logical operators, it is either a copy/paste error and, therefore, a bug, or it is simply duplicated code and should be simplified. In the case of bitwise operators and most binary mathematical operators, having the same value on both sides of an operator yields predictable results and should be simplified as well.

        Note that this rule will raise issues on a == a and a != a expressions which are sometime used to detect NaN values. It is recommended to use instead math.IsNaN() or an equivalent function. This will improve code readability.

        Noncompliant code example

        func main() {
          v1 := (true && false) && (true && false) // Noncompliant
        }
        

        Compliant solution

        func main() {
          v1 := (true && false) // Compliant
        }
        

        Exceptions

        This rule ignores *, +, << and =.
