Often times out of laziness we simply pass errors up a call chain. For example, let’s look at this function that formats hours and minutes into a time message: func formatTimeWithMessage { formatted, err :=formatTime if err !=nil { return "", err } return "It is " + formatted + " o'clock", nil }function can be called many other places within our application or library. If all we do is pass along the raw error, when the error is eventually printed, it gets really hard to tell where exactly the error originated from.
