package utility

import (
      "io/ioutil"
      "net/http"
      "time"
)

func GetHtmlFromUrl(websiteUrl string, timeoutValue int) (string, error) {
      timeout := time.Duration(timeoutValue) * time.Second
      client := http.Client{Timeout: timeout}

      resp, err := client.Get(websiteUrl)
      if err == nil {
            reader := resp.Body
            defer reader.Close()

            body, err := ioutil.ReadAll(reader)
            if err == nil {
                     return string(body), nil
            }
      }

      return "", err
}

vs
func GetHtmlFromUrl(websiteUrl string, timeoutValue int) (string, error) {
      timeout := time.Duration(timeoutValue) * time.Second
      client := http.Client{
Timeout: timeout,
}

      resp, err := client.Get(websiteUrl)
      if err == nil {
            reader := resp.Body
            defer reader.Close()

            body, err := ioutil.ReadAll(reader)
            if err == nil {
                     return string(body), nil
            }
      }

      return "", err
}

My question is why I need to add a comma at the the end like this, I was thinking that comma is useless in other language i.e. c#, it seems that my vi editor enforce me to do that, I guess the golang compiler might report error if I missed the comma
      client := http.Client{
Timeout: timeout,
}

Any comments?

build environment
centos latest version
golang 1.7.1
