I have a function like this:

var api = {
    getProduct : function(callback){
          //code anything
          //resp data 
          if(typeof callback == "function") callback(resp);
     }
}

There is anyway use like

var data = api.getProduct(function(resp){
  return resp;
});
console.log(data);

I need do something outside callback

`return callback(...)` ? – Grundy Oct 30 '15 at 08:09
@Grundy isn't `return callback(...)` a bit smelly? – caub Oct 30 '15 at 08:20
@crl, why i think this? :-) – Grundy Oct 30 '15 at 08:23
@crl :-D this a typo, it should be: _why **you** think this?_ :-) – Grundy Oct 30 '15 at 08:34

because a callback is most often something asynchronous – caub Oct 30 '15 at 08:39
@OP you are mixing synchronous and async data, it should be `api.getProduct(function(resp){console.log('deal with resp here')})` or the same with Promises – caub Oct 30 '15 at 08:55
