        // React

        function App() {

        }

        ReactDOM.render(<App />, document.getElementById('root'));

        // Vue
        const app = Vue.createApp({
            data() {
                return { message: 'Hello, Vue!' }
            },
            template: '<h1>{{ message }}</h1>'
        });
        app.mount('#app');
