Q.js - Using deferred

Question

How do I get the value of the text from the example below?

Q.js has an example on using Deferred:

var deferred = Q.defer();
FS.readFile(\"foo.txt\", \"ut         


        

Answer 1

Q = require('q');
FS = require('fs');

function qread() {
  var deferred = Q.defer();
  FS.readFile("foo.txt", "utf-8", function (error, text) {
    if (error) {
  deferred.reject(new Error(error));
    } else {
  deferred.resolve(text);
    }
  });
  return deferred.promise;
};   

var foo = qread();

setTimeout(function() {
  console.log(""+foo);
},1000);

It's strange you cannot see the output for console.log(foo). Dont' know why.
