When the program runs, my h1 heading disappears.

When the program runs, the h1 heading I wrote in the html file disappears and only the paragraph with the message is left. How can I make the h1 heading stay above the paragraph?

Using document.write() clears the previous html code. To keep your header, avoid using document.write() or include your header as part of the input for document.write().

To add a paragraph with a given message after the first <h1> element of the page, you could try 

let messageParagraph = document.createElement("p");
let messageText = document.createTextNode("Your message here");
messageParagraph.appendChild(messageText);

let headerHeading = document.querySelector("h1");
headerHeading.insertAdjacentElement("afterend", messageParagraph);

where you create a paragraph, add text to it, and insert it after your <h1> element.

If security is not a concern and you want to add the paragraph to the end of the document's body, you could use document.body.innerHTML += "<p>Your message here</p>"; instead.
