Initializing Router Service

Create a new service

/services/Router.js

const Router = {
    init: () => {
        
    },    
    go: (route, addToHistory=true) => {

    }
}

export default Router;

And let's import this new service from app.js and call it from DOMContentLoaded

import Router from './services/Router.js';

window.addEventListener("DOMContentLoaded", () => {
    app.router.init();
    loadData();
});
