Not the most efficient, but simple and clear.
func printSlice(a []string) string {
q := make([]string, len(a))
for i, s := range a {
q[i] = fmt.Sprintf("%q", s)
}
return fmt.Sprintf("[%s]", strings.Join(q, ", "))
}

[go-nuts] How to print arrays with commas and brackets
Hello Nalin,
If you use a slice of strings to hold your data, as an alternative you could go
with
fmt.Printf("[%s]", strings.Join(your_slice_of_strings, ","))
Cheers!

Re: [go-nuts] How to print arrays with commas and brackets
I tried to print array with brackets and commas in golang. I want to
get
array like this.
["record1", "record2". "record3"]
Encode the array to JSON:
```
package main
import (
"encoding/json"
"fmt"
"log"
"os"
)
func main() {
strings := [3]string{"foo", "bar", "baz"}
stringsJson, err := json.Marshal(strings)
if err != nil {
log.Fatal("Cannot encode to JSON ", err)
}
fmt.Fprintf(os.Stdout, "%s", stringsJson)
}
```
Output:
["foo","bar","baz"]
