Go lookin' all JavaScript

better.go

func myMethod (myThing myType) (retVal string, val int) {
  
  val = 0
  retVal = "Farhan"
}

func main() {

  if _, err := myType.myMethod(); !err {
    // do stuff
  }
  
  

  done := make(chan bool) // init a channel of bool

  // anonymous function
  go func() {
    
    myType.MyMethodDoingStuff()
    
    done <- true  // when method's done, put true on the channel
    
  }()  // yo, goroutine! execute yo'self!
  
  somethingElse.DoSomethingElse()
  
  val bool;
  
  val <- done  // channel will block until a bool is put on it
               // so program won't exit until goroutine is done
  
}

Or you could assign a value for what pops out of done
