how do we use an <h2> tag to write a var directly into the HTML file?

Hi everyone,

I was trying to put the shoutOut variable directly into the Index.html file using the document.write() method. if we put just the variable shoutOut into the code like document.write(shoutOut), the size of the text is really small. I wanted to use the <h2> tag to increase the font size, does anyone know how to do that? below is my code, but it prints out the word " shoutOut " instead of the value in the variable shoutOut. Any help would be useful.

var shout = prompt("Write something");

var shoutOut = shout.toUpperCase();

shoutOut += "!!!!";

document.write("<h2>shoutOut</h2>");

Thank you again, appreciate your help.

Cheers.

There are a number of ways to do this, but the simplest is probably concatenation (joining strings together) with the "+" operator:

document.write("<h2>" + shoutOut + "</h2>");

But be aware that while this will display on the page in the browser, it does not add anything to the index.html file.
