Sublime Text 3 build problem Haml/jQuery $ is not defined

Question

I'm using the sublime text 3 editor

Error is the following

The loading of jquery reference should be correct..

Is like this on file.haml

%script{ :src => "js/jquery-3.3.1.min.js" , :type => "text/javascript"}
%script{ :src => "js/jquery-ui.min.js" , :type => "text/javascript"} 
%script{ :src => "js/submitEvent.js" , :type => "text/javascript"}

My file.js works the same on my webpage but, if i try to build it ...give this error

can someone explain to me why?

(function (exports, require, module, __filename, __dirname) { $(document).ready(function(){
                                                              ^

A website uses jQuery differently than Node does. In the browser, jQuery is assigned to global variable (jQuery/$). Node uses require() or ES6 imports to make jQuery accessible in a script.

If you need your code to run in both, Node and the browser, you need to use a bundler such as Webpack or Browserify. However, to expains these is beyond the scope of your question. I'd start by reading a tutorial and come back when you have specific questions along the way.
