// Example of outdated approach to DOM manipulation
document.getElementById('myDiv').innerHTML = 'New content';

// Example of modern approach using Virtual DOM (React)
// More efficient for frequent changes
const myDivElement = React.createElement('div', null, 'New content');
ReactDOM.render(myDivElement, document.getElementById('myDiv'));
