Should I return success callback return value?

Is it conventional for parent function to return their child success callbacks or does it just depend on a case by case basis?

var cb = function(){
    return 1;
}

function ret_cb(succ_cb) {
    return(succ_cb ? succ_cb() : 1);
}

var succ = ret_cb(cb);
console.log(succ);

//or

function no_ret_cb(succ_cb) {
    if(succ_cb){
        succ_cb();
    }
    return 1;
}

succ = no_ret_cb(cb);
console.log(succ);

This would mainly be the reason I would use the callback

//functional way

succ = ret_cb(cb);

//vs

var some_value = "hello";
succ = ret_cb();
succ &= cb(some_value);

It's case by case.

It is rare for a function to take a callback and not be either asynchronous (in which case there is no return value from the callback to return until later) or operating in a loop (in which case there isn't one result of running the function to return).
