Javascript script load order - undefined function

I am working in a not very nice template that made me load some scripts with JS as I have no control over the order there. I am trying to load a library, but when I try to call it I get an undefined error.

$.getScript( "js/velocity.min.js").done(function(){
    $('body').velocity({ width: 200})
});

      

        
        
        
      

    

Get error: Unacceptable TypeError: $ (...). speed is not a function

How can it be? I just downloaded you!

Well there was a conflict with another script that needs to be loaded, to fix this, I wrap the speed code in a closure and set "define" to null inside it.

(function($){
    var define = null;
    //then velocity code is here
})(jQuery)
