title: Express next function, what is it really for?
body: <p>Have been trying to find a good description of what the <code>next()</code> method does. In the Express documentation it says that <code>next('route')</code> can be used to jump to that route and skip all routes in between, but sometimes <code>next</code> is called without arguments. Anybody knows of a good tutorial etc that describes the <code>next</code> function?</p>
