The error is self explanatory. You define variable "kk" but never use it.
If you don't care about the return value of io.Writer() simply omit the
assignment; just call the function. Or explicitly assign to the special "_"
placeholder var to show that you know the function returns a value and you
are deliberately ignoring it. Beyond that the statement doesn't make any
sense since io.Writer is an interface type. Not a function you call. Also,
bytes.NewBuffer() returns an object which implements the io.Writer
interface. You don't need to do anything else to turn it intoan io.Writer.
