JavaScript document.write basic syntax

document.write('Write the text you want to present here');

JavaScript document.write line break example

<script language="javascript">
document.write('This is the first line<br>');
document.write('This is the second line<br>');
document.write('<p>This is The first paragraph</p><p>This is the second paragraph</p>');
</script>

The output of the above example

This is the first line
this is the second line

This is the first paragraph

This is the second paragraph

The HTML <br> line break tag and <p> paragraph tag are used in the example. If you just output one line at a time, you can use the <br> line break tag. If you want to output a paragraph, use the HTML <p> paragraph tag. The difference between the two is that <br> will only change one line at a time, while <p> will change two lines at a time, and each set of <p></p> tags will have a line spacing.
