nodejs: Async.series only executes the first function and stops

Question

On executing the following code, only first function of the async.series executes.

var fs = require("fs");
var async = require("async");
var buffer = new Buffer(10);
var read = "";
var readByt;
async.series([      
    function(callback) {
         console.log("console: 1");
    },
    function (callback){
        console.log("console: 2");
    }
],function(){});

The output is given below:

c:\>node fr.js
}}}c:/log.txt
File closed successfully.

If the following is edited as mentioned below:

var fs = require("fs");
var async = require("async");
var buffer = new Buffer(10);
var read = "";
var readByt;
async.series([
    function(callback) {
         console.log("test");
    },
    function (callback){
        console.log("console: 1");
    }
   function (callback){
        console.log("console: 2");
    }
],function(){});

The output changes as below:

c:\>node fr.js
test

How do i get all the functions in the async.series to execute?

Answer 1

I think you need to invoke the callback argument supplied in the array of functions to instruct the async module to invoke the next function.
