I know it is a bit picky  but all the answers so far are not quite right   The point of path join   is to eliminate the need for the caller to know which directory separator to use  making code platform agnostic    Technically the correct answer would be something like   var path   require  path     fs readFile path join   dirname               foo bar       I would have added this as a comment to Alex Wayne s answer but not enough rep yet   EDIT  as per user1767586 s observation
