If you are using a version of Go >= 1.10, then you should be using the newer strings.Builder pattern as follows:
package main
import (
"strings"
"fmt"
)
func main() {
var sb strings.Builder
for i := 0; i < 100; i++ {
sb.WriteString("a")
}
fmt.Println(sb.String())
}
For older version, you should be looking to use the bytes.Buffer instead:
package main
import (
"bytes"
"fmt"
)
func main() {
var buffer bytes.Buffer
for i := 0; i < 100; i++ {
buffer.WriteString("a")
}
fmt.Println(buffer.String())
}
