I'm a totally newbie in node.js. I'm trying to implement a browser performance tool using node.js, so I have the following piece of code:

 for(var j=0; j < 14; j++) {

        // Create a new instance of HttpWatch in Firefox

        var control = new ActiveXObject('HttpWatch.Controller');

        var plugin = control.Firefox.New();

        // Start Recording HTTP traffic

        plugin.Log.EnableFilter(false);

        // Clear Cache and cookier before each test

        plugin.ClearCache();

        plugin.ClearAllCookies();   

        plugin.ClearSessionCookies();

        plugin.Record();

        // Goto to the URL and wait for the page to be loaded

        plugin.GotoURL(url);

        control.Wait(plugin, -1);

        // Stop recording HTTP

        plugin.Stop();

        if ( plugin.Log.Pages.Count != 0 )

        {           

           // Display summary statistics for page

           var summary = plugin.Log.Pages(0).Entries.Summary;

           //WScript.Echo( Iteration number  + j + for + url +    Total time to load page in (secs):  + summary.Time);

           cache[i].value.push(summary.Time);

        }

        // Close down Firefox

        plugin.CloseBrowser();

      }

I'm using httpwatch to measure the performance values, which are going to be stored in a MySQL database.
However, when I run:

node test.js

I get:

C:xampphtdocstestbrowser-perf>node test.js



C:xampphtdocstestbrowser-perftest.js:37

                var control = new ActiveXObject('HttpWatch.Controller');

                                  ^

ReferenceError: ActiveXObject is not defined

How can I create a similar object as ActiveXObject in node.js and obtain the same desired results?
