  const Gtk = imports.gi.Gtk;
  const WebKit = imports.gi.WebKit2;

  class SimpleBrowser {
    constructor() {
        this.application = new Gtk.Application({
            application_id: 'com.example.SimpleBrowser'
        });

        this.application.connect('activate', () => {
            this.window = new Gtk.ApplicationWindow({
                application: this.application,
                title: "Simple Browser",
                default_height: 600,
                default_width: 800
            });

            this.webview = new WebKit.WebView();
            this.window.add(this.webview);
            this.webview.load_uri("http://www.example.com");

            this.window.show_all();

  app.application.run(ARGV);

In general this sounds pretty cool: GJS is built on the SpiderMonkey JavaScript engine. It utilizes GObject Introspection to provide access to the GNOME APIs using ECMAScript 2021 JavaScript.

Just don't compare it with Node.js; it's something else. No, your code might not run in that environment; APIs are most likely not compatible.
