My personal preference is this: var assets = "/images" var sounds = assets+"/sounds" I always use absolute paths (`/images/...`), it feels less prone to error, to me. It is also more fool proof to use `var sounds = assets+"/sounds"` because even if `assets` had a trailing slash and you ended up with `/images//sounds`, it would still resolve to `/images/sounds`. The one disclaimer being that it depends on your request handler. Apache seems to handle it fine (at least certain versions/configurations, see http://www.amazon.com//gp//site-directory//ref=nav_sad). With the other way you'd end up with `/imagessounds`, not so fool proof :) There is also the option of checking for double slashes and cleaning them up. Not an option with the other approach.
