javascript - looping promises in nodejs -

i learning promises in nodejs, below example code. output of below code test - 1 test - 2 test - 3 test - 4 var q = require('q'); var promise = q.when('test'); promise.then( function(val) { console.log(val + '-' + '1'); }); promise.then( function(val) { console.log(val + '-' + '2'); }); promise.then( function(val) { console.log(val + '-' + '3'); }); promise.then( function(val) { console.log(val + '-' + '4'); }); i know how can write same code using loop. this isn't specific promises. if you're creating callbacks in loop, you'll need closure scope , other it's quite standard. however, simplest way specific case use single callback only, attached same promise anyway , receive same value. use require('q').when('test').then(function(val) { (var i=1; i<=4; i++) { console.log(val + '-' + i); } });
