Why is JQ not working in bootstrap?

Question

JavaScript

Heeeelp guys!

I am making a new layout for the block on bootstrap, but for some reason jq does not work. IDE writes that the $ sign is generally something foreign.
But, if I make effects using bootstrap itself, then they work, simple js too. I've been toiling for 3 hours already, Google does not help.

I am attaching a link to the code:

Answer 1

1. In layout, you can not specify type="text/javascript" - it is set by default for the script Just by the way.
2. And try to replace your redi document with this option, with jquery no conflict

"use strict";

console.log('script.js'); // убидитесь в подключение вашего файла. 

(function ($) {
  $(function () {
    // тут набирайте свои обращения.
  });
}) (jQuery);

Answer 2

Maybe just an old version of jQuery?
