func GetFileBaseName 

func GetFileBaseName(path string) string

Name returns the last element of path without file extension. Example: /var/www/file.js -> file file.js -> file

func GetFileDir 

func GetFileDir(path string) string

Dir returns all but the last element of path, typically the path's directory. After dropping the final element, Dir calls Clean on the path and trailing slashes are removed. If the `path` is empty, Dir returns ".". If the `path` is ".", Dir treats the path as current working directory. If the `path` consists entirely of separators, Dir returns a single separator. The returned path does not end in a separator unless it is the root directory.
