as everyone knows Windows does paths with backslashes where Unix does paths with forward slashes. node.js provides
path.join() to always use the correct slash. So for example instead of writing the Unix only
'a/b/c' you would do
However, it seems that despite this difference if you do not normalize your paths (e.g. using path.join) and just write paths like
a/b/c node.js has no problem with running your scripts on Windows.
So is there any benefit over writing
'a/b/c'? Both appear to work regardless of platform...
Windows filesystems have no problem using either forward or backward slashes as path separators (this has been the case since back in the DOS days). The only real issue is that Windows command-line processors (or, more specifically, Windows-native command-line utilities) tend to interpret forward slashes as option specifiers rather than path components. Therefore, you need a backslashed path if you need to pass a path to a Windows command run as a subprocess. Also, Windows API calls (and methods from higher-level languages that call the Windows API) that return paths will use backslashes, so even if you aren't passing them to subprocesses, you'll need to normalize them.
path.join will take care of unneccessary delimiters, that may occur if the given pathes come from unknown sources (eg. user input, 3rd party APIs etc.).
path.join('a','/b') will all give
Without using it, you usually would make expectations about the start and end of the pathes joined, knowing they only have no or one slash.
