JavaScript Script Loader

lodar.js

;(function (name, self, d) {
    self[name] = function (src, cb) {
        cb = cb || function () {};

        var newScriptTag = d.createElement('script'),
            firstScriptTag = d.getElementsByTagName('script')[0];

        newScriptTag.src = src;
        newScriptTag.async = true;
        newScriptTag.onload = newScriptTag.onreadystatechange = function () {
            (!this.readyState || this.readyState === 'loaded' || this.readyState === 'complete') && (cb());
        };
        firstScriptTag.parentNode.insertBefore(newScriptTag, firstScriptTag);
    }
})('lodar', this, document);

Awsome!

I figured it out and changed it around to suit my needs!
