Your code is using `document.write()`. This is a very old and problematic way to add content to a page. It can severely slow down your site, especially on slow networks, and can also create security vulnerabilities. Modern web development has much better and safer ways to manipulate the page.
document.write('<p>Hello World</p>');Use modern DOM manipulation methods, like `createElement` and `appendChild`, to add content to the page safely and efficiently.
const newParagraph = document.createElement('p');
newParagraph.textContent = 'Hello World';
document.body.appendChild(newParagraph);Modern DOM APIs are faster, safer, and more predictable than `document.write`. They don't block page rendering and are not susceptible to the same security risks, making them the standard for any modern web application.
