javascript - Node.js meteor.js fibers and loop -

okay learning fibers , dont know how implement "waiting end of loop inside fiber"

now have code works without problem.

        if (meteor.isserver) {          function checkifiownthisitem(callback) {            settimeout(function() {                 callback("this callback");             }, 500);         }                     var f = fiber(function() {             var fiber = fiber.current;              checkifiownthisitem(function(str) {                 fiber.run(str);             });              str = fiber.yield();             console.log(str);         });          f.run();      } 

and need replace settimeout ...for...

        _.each(mybank.items,function(loopitem,key,list){         if (loopitem.itemid == item.itemid) {             ownitem = true;             countofowniteminbank = parseint(loopitem.number);         }     });  

the whole point first check if own item (own item true) , can whatever hell want need sure ownitem true

it sounds starting memories fibers/threads in desktop programming , trying map exact equivalence. remember world. don't think way. fibers more not waiting around answer come time.

i bet if take smaller steps, think less, , html/js want, come here when hit stopping block, make progress.

ownership of items, example, commonly expressed field in document, ownerid, matching current userid
