        Once control flow has been moved out of the current code block, any subsequent statements become effectively unreachable.

        Why is this an issue?

        More Info

        Jump statements (return, break and next) move control flow out of the current code block. So any statements that come after a jump are dead code.

        Noncompliant code example

        def foo(a)
          i = 10
          return a + i    # Noncompliant
          i += 1          # dead code
        end
        

        Compliant solution

        def foo(a)
          i = 10
          return a + i
        end
