How to omit javascript loading in page footer?

Question

JavaScript

The HEAD of the document contains jQuery.js and Bootstrap.js .
If you lower them down on the page (so that they are loaded after the entire page is loaded), then naturally such code on the page as $(function(){...});
What is the best way to do this, or to score and leave it as it is? Or something to replace $(function(){}); ?

Answer 1

And if several such places are scattered throughout the code?

Well, in extreme cases, you can throw in a hat:

window.$ = function(f){
   window.addEventListener("load", f);
};

Answer 2

maby $(function(){...}); move even lower than bootstrap and jquery loading?
