Is it correct to use multiple "return" statements in a function?

Answer 1

If there are many conditions that lead to return, then there can be switch ... case and its ability to fall through several conditions, like this:

function test (a) {
    switch (a) {
        case 1:
        case 2:
        case 3:
        case 4:
        case 5:
        case 6:
            return;
        case 7:
            // other code
            break;
    }
}

Answer 2

For example, if you rely on NRVO (Named Return Value Optimization) in C++, then it's better to use a single return.

Answer 3

It depends on the code-style adopted in the command, for example, I think that using more than two returns everywhere except equals is not very good.

Answer 4

Well, depending on what kind of function, and so, of course you can.

Answer 5

The multiple return, as well as the break, continue, switch and throw statements, are nothing more than disguises for the goto statement, which has been fought over for the past few decades. So, if you are not afraid of goto, then use it to your health.
