-- import "github.com/zenixls2/fastprint"

The fastprint package provides fast string concat functionality in Go.

With large quantity of []string or [][]byte concat, you may use strings.Join(array, "") or bytes.Join(array, []byte{}), here we provide something else with less memory allocation and faster operations.
