Golang : Concatenate (combine) buffer data example

At previous tutorial on how to concatenate ( combine ) strings data, a reader asked how to concatenate data inside a buffer.

In Golang, the += symbol equals to x = x + somethingnew and we will use the += to combine the buffer data(which is converted to string type with the built in String() and strconv.Itoa() functions.

Here you go :

 package main

 import (

 func main() {
  var buffer bytes.Buffer

  for i := 0; i < 2; i++ {

  s := buffer.String()

  // s is now aa

  for i := 0; i < 8; i++ {
 s += strconv.Itoa(i)

  // s is now aa01234567

  s += buffer.String()

  // s is now aa01234567aa


Output :


Happy Coding!
