     sliceA := array[0:5]
     append(sliceA, 4)
     fmt.Println(sliceA)
}

Error : append(sliceA, 4

Answer 1

Per the Go docs:

The resulting value of append is a slice containing all the elements of the original slice plus the provided values.

So the return value of 'append', will contain your original slice with the appended portion.
