Golang : If else example and common mistake



Tags : golang if-else-then

Maybe I'm so used to PHP before moving to Golang that I keep making the same mistake with IF-ELSE-THEN statement in Golang.

This is a good example of IF-ELSE

 package main

 import (
 "fmt"
 "os"
 )

 func main() {
 if os.Args[1] == "Hello" {
 fmt.Println("Hello World")
 } else {
 fmt.Println("GoodBye World")
 }
 }

and bad example, which WILL NOT compile because the { is one line below 'IF`

 package main

 import (
 "fmt"
 "os"
 )

 func main() {
 if os.Args[1] == "Hello" 
 { // will not compile
 fmt.Println("Hello World")
 } else {
 fmt.Println("GoodBye World")
 }
 }
