Adding JavaScript from JavaScript

JavaScript can easily download and run additional JavaScript

You don't need to use Ajax to download additional JavaScript code to run on your page. All that you need to do is to add the appropriate script tags into the head of your existing page to download additional JavaScripts. You then either have the code in the end of that script that calls the functions within the new script or simply use feature sensing to check if the functions have been downloaded yet.
