The
path.basename() method is used to get the filename portion of a path to the file. The trailing directory separators are ignored when using this method.
Syntax:
path.basename( path, extension )
Parameters: This method accepts two parameters as mentioned above and described below:
- path: It is the file path that would be used to extract the filename.
- extension: It is an optional file extension that would be removed from the returned string.
Return Value: It returns a string with the filename portion of the path. It throws an error if the path or the extension parameters are not string values.
