golang append() evaluated but not used

Question

func main(){
     var array [10]int
     sliceA := array[0:5]
     append(sliceA, 4)
     fmt.Println(sliceA)
}

Error : append(sliceA, 4

Answer 1

sliceA =append(sliceA, 4) append returns a slice containing one or more new values. Note that we need to accept a return value from append as we may get a new slice value.
