I was having a problem with the strings.Builder type in GO.
Attempted to run the example code verbatim and GO still responds with:
undefined: strings.Builder
Any clues as to what the problem can be, there's been not other problems at all.
package main
import (
"fmt"
"strings"
)
func main() {
var b strings.Builder
for i := 3; i >=1; i-- {
fmt.Fprintf(&b, "%x...", i)
}
b.WriteString("ignition")
fmt.Println(b.String())
}
