angularjs - Should I use ''return" with my callback function in Javascript?

Question

I am using asynchronous functions in my JS application wrapped with my own functions that receive callback inputs. When i call the callback function, do I need to use the "return" keyword? does it matter? whats the difference?

eg:

var getData = function(callback){
    // do some aysnc db stuff...
    return callback(results);
    // or just
    callback(results);
}

PS: I am writing a hybrid mobile appiliction using javascript.

No, callback should not be used with return.
I'd never expect a callback-function to return a value. The callback replaces the return in terms of passing a value when the (async) computation is done.

You can use this Syntax return callback(result) as a shortcut for like callback(result); return; but it may confuse some further Team-member, what kind of value callback might return.
This is actually a task for your minifyer, to create such code; not yours.
