Creating a custom function — concatBytes

Suppose you want to create the concatBytes function, which is very similar to the concatRunes function you've previously seen in the theory.

Please modify the concat function template below so the function is called concatBytes and properly uses the WriteByte() method within it.

Write a program in Go
package main

import (
"fmt"
"strings"
)

// Modify the concat function template below to properly implement the concatBytes function
func concat?(bytes ...byte) string {
var builder strings.Builder
for _, x := range bytes {
builder.Write?(x)
}
return builder.String()
}

func main() {
fmt.Println(concatBytes('J', 'B', 'A', 'c', 'a', 'd', 'e', 'm', 'y'))
}
