This tutorial shows how to concatenate strings in Go language using the strings.Builder and bytes.Buffer methods.

Example 1: Using strings.Builder Method

package main

import (
    "strings"
    "fmt"
)

func main() {
    
    var sb strings.Builder

    for i := 0; i < 1000; i++ {
        sb.WriteString("vin")
    }

    fmt.Println(sb.String())
}

Output:

vinvinvinvinvinvinvinvinvinvinvinvinvinvinvinvinvinvinvinvin...

Example 2: Using the bytes.Buffer Method

package main

import (
    "bytes"
    "fmt"
)

func main() {
    var buffer bytes.Buffer

    for i := 0; i < 1000; i++ {
        buffer.WriteString("vin")
    }

    fmt.Println(buffer.String())
}

Output:

vinvinvinvinvinvinvinvinvinvinvinvinvinvinvinvinvinvinvin...
