title: Cleaner way to iterate through array + create a string from values
body: <p>With this code, is there a better way to loop through all the users and create a new string containing all their <code>Nick</code> values?    </p>
  
  <pre><code>package main
  
  import "fmt"
  
  type User struct {
      Nick     string
  }
  
  
  func main() {
      var users [2]User
      users[0] = User{ Nick: "Radar" }
      users[1] = User{ Nick: "NotRadar" }
      names := ":"
      for _, u := range users {
          names += u.Nick + " "
      }
      fmt.Println(names)
  
  }
  </code></pre>
