Node.js url.parse() and pathname property

Question

I\'m reading a getting started book on node.js called The Node Beginner Book and in the code below (given in the book) I don\'t understand the significance

Answer 1

pathname is the path section of the URL, that comes after the host and before the query, including the initial slash if present.

For example:

url.parse('http://stackoverflow.com/questions/17184791').pathname    

will give you:

"/questions/17184791"
