Dead Code (ARCH5188)

Key go.quality.dead-code · Severity info · Category quality

Unreachable code after a return never runs, misleads readers, and adds maintenance burden. Remove it.

Incorrect

func score(n int) int {
    if n > 0 {
        return n * 2
    }
    return 0
    log.Println("computed") // unreachable
}

Correct

func score(n int) int {
    if n > 0 {
        return n * 2
    }
    return 0
}

Fix

Delete unreachable statements; if the code is genuinely needed, restructure the control flow.
