I'm currently writing my thesis, using LaTeX. As the programming part of my thesis was mostly done in Javascript, I have to include some bits of Javascript source code in the LaTeX document. For this I'm using the listings package. With this package you can "include the source code of any programming language within your document". Unfortunately Javascript is not in the list of supported programming languages. (In return, the list contains languages like Oberon-2, Promela or RSL, which are probably being used way more often than Javascript ... er.)
Luckily @awendt pointed me to these links: Javascript Quelltexte in LaTeX and a thread on a mailinglist. I changed those examples only a bit, I'm posting my result here mainly in the hope it will produce a Google hit for "javascript latex source code" :-)
