HTML 4.01 indicates the following about <pre> ... </pre>:

<pre> ... </pre> Preformated Text Definition:
Forces the browser to display the exact formatting, indentation, and white space that the original text contains. This is valuable in reproducing formatted tables or other text, such as code listings.
Suggested Style/Usage of <pre> ... </pre>:
Within the <pre> ... </pre> block, you can break lines by pressing Enter, but try to keep line lengths at 80 columns or fewer because <pre> text is typically set in a monospaced font. This tag is great for presenting text-only information.

Notes on scripts that are placed inside <pre> ... </pre> block:

the font family changed from default to a monospaced font on both document.write() and document.writeln();
the document.write() doesn't wrap the lines of text;
the document.writeln() wraps the next instance of text to the next line.
