Provides a way to enumerate items in a collection.
new Enumerator(collection)

The collection argument is any collection object.

Collections differ from arrays in that the members of a collection are not directly accessible. Instead of using indices, as you would with arrays, you can only move the current item pointer to the first or next element of a collection.

The Enumerator object provides a way to access any member of a collection and behaves similarly to the For...Each statement in VBScript.

The following code shows the usage of the Enumerator object:

function ShowDriveList()
    var fs, s, n, e, x;
    fs = new ActiveXObject("Scripting.FileSystemObject");
    e = new Enumerator(fs.Drives);
    s = "";
    for (;!e.atEnd();e.moveNext())
        x = e.item();
        s = s + x.DriveLetter;
        s += " - ";
        if (x.DriveType == 3)
             n = x.ShareName;
        else if (x.IsReady)
             n = x.VolumeName;
             n = "[Drive not ready]";
        s +=  n + "<br>";
