You cant really do that in ES6.You'd have to use a co-routine framework (and a "thunkifier") and a generator that would yield some stuff. something like co(function *(){ for(i in uids){ users[i] = yield thunkify(load_users)(uids[i]); } }); While generators are useful, they dont make async code look like sync code.
