index.js which I run through the command line with the command node index.js

(function(){
  "use strict";
import $ from 'jquery';
$(document).ready(function($) {
  console.log('СЕРВЕР ЗАПУЩЕН'); 
});
})();

Result: import $ from 'jquery'; - SyntaxError: Unexpected identifier
QUESTION: What does the error mean I KNOW, can't figure out why?

Answer 1

why do you node index.jsneed it when you need it npm run startfor development and npm run buildfor building sales.
node index.jslaunches the node with the index.js file, the node does not understand imports and gives an error.
