Alternatively to writing a new element, using the sample you have in the HTML tab <h1 id= "x"></h1> any of these three sets locate and dynamically set the element's inner HTML. I'm using onload() because otherwise the [JS] tab would load before the document element is ready. window.onload = function() { var el = document.querySelector("#x"); el.innerHTML = x; el = document.getElementsByTagName("h1")[0]; el.innerHTML = x; el = document.getElementById("x"); el.innerHTML = x; }

Use the + operator to concatenate the values: var x = 100; document.write("<h1>" + x + "</h1>");
