<p> tag on document.write.

The p tag adds HTML formatting to the statement you right. You don't have to do it this way.

You can format the text on document.write by adding it as a src attribute.

<div id = "formattngForDocumentWrite">

    <script src="app.js">
    var paragraph = document.write("This is a message");
    </div>
</div>

And style it with your CSS

#formattngForDocumentWrite {
    color: red;
    font-size: 1.3em;
}

I had the same question... I think we also have written programs with document.write without using < p > and < / p > tags. I tried just removing those, and it still seems to work... the text looks smaller though... So what exactly will happen if we have this code as a part of a larger program and do not use the < p > tags?

For testing code purposes, tags doesn't really matter if you just need to know the data. The main purpose of tags is to tell the browser how to display the content.

For me, I still add the paragraph tag because Inserting it starts the text on the next line making it more readable if you have multiple contents on a single page. You can check document.writeln() too.
