Laravel response SPA?

Question

Laravel

Hello. Let's say on the backend I have the following code:

if(...) {
        return response()->json([
            'message' => 'Some message!';
        ], 401);
} else {
        return response()->json([
            'message' => 'Other some message!'
        ], 401);
}

On the frontend, having received one of the answers, I need to implement different logic. But the response code is the same. this often happens. How to do it right? Should I check message in if? Didn't see them doing that.
And the second question is this 'message' in json, which is used everywhere, is it needed for debugging purposes, or can it be output to the user in flash messages?

Answer 1

Evil uncles do not allow you to send other variables, except for message?

Answer 2

return response()->json([
            'message' => 'Some message!';
            'code' => 1;
        ], 401);
