title: node.async parallel : can we create dynamic texts to denote tasks?
body: <p>Inside node async methods, we define tasks as "one" or "two" like in the example below. Is there a way to make that text dynamic ?</p>
  
  <pre><code>    var async = require("async");
      async.parallel({
          one: function(callback){
              setTimeout(function(){
                  callback(null, 1);
              }, 200);
          },
          two: function(callback){
              setTimeout(function(){
                  callback(null, 2);
              }, 100);
          }
      },
      function(err, results) {
          console.log(results); // results is now equals to: {one: 1, two: 2} 
      });
  </code></pre>
