async.parallel: Type Error, task is not a function
<p>What is wrong with this code ?</p>

<pre><code>async = require("async");
fs = require("fs")

async.parallel(['calc.js','index.js'], fs.stat, function (err, results) {  
if (err){
console.log(err);
}
else{
    console.log(results);
}
});
</code></pre>

<p>When I try to run this little peice of code, I get the error mentioned below -</p>

<pre><code>/home/gaurav/node-exp/node_modules/async/dist/async.js:4819
        task(rest(function (err, args) {
        ^

TypeError: task is not a function
</code></pre>

<p>I was following a nodejs tutorial and I am very new to node js so pardon me if the question is very naive</p>
