Question

I have the following function that takes a command from terminal and prints something based on input. It seems simple enough, if the user types \'add\' the system prints a line,

Also you can use recover() for check existing index of slices

func takes(s []string, i int) string {
    defer func() {
        if err := recover(); err != nil {
           return
        }
    }()
    return s[i]
}

if takes(inp,0) == "add" {
   fmt.Println("you typed add")
} else {
   fmt.Println("you didn't type add")
}
