What is the alternative to jQuery(this) in YUI?

In most cases, jQuery(this) is done inside event callbacks to wrap the subscribed element with the jQuery API. In YUI3, that's done for you automatically. The this in event callbacks is the Node instance that was subscribed from.

Y.one('#readygo').on('click', function (e) {
    this.append("<p><code>this</code> is already a YUI 3 wrapped Node instance.</p>");
});

You may find JS Rosettastone useful. I found it invaluable when I moved to YUI 3 and I will not move back.
