 URL  (url)
In the previous section, you saw the url.parse() method used, and that’s just one thing 
the URL module offers. Some others are as follows:
•  URL – Okay, this is going to sound weird, but the URL module  
exposes the URL class, and the URL class is where a large chunk of  
the functionality of this module resides. For example, the  
url.URL.hash property returns the fragment portion of a URL  
(e.g., new url.URL("
http://mysite.com/page.html#sectionA"
).
hash will have the value #sectionA). Similarly, you can get the host (which 
will include the port, if specified), the hostname (which will not include the 
port), the username and password portion of a URL (if specified), and the 
port or protocol, in the same way, all properties of a URL instance.
•  url.pathToFileURL() and url.fileURLToPath() – Respectively, these 
methods ensure that a path is resolved absolutely and that the URL 
control characters are correctly encoded when converting into a file 
URL and that correct decoding of percent-encoded characters in a file 
URL is done while ensuring the result is a valid cross-platform path.
