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

Here's an example:

var url = "https://u:p@www.example.com:777/a/b?c=d&e=f#g";
var parsedUrl = require('url').parse(url);
...
protocol  https:
auth      u:p
host      www.example.com:777
port      777
hostname  www.example.com
hash      #g
search    ?c=d&e=f
query     c=d&e=f
pathname  /a/b
path      /a/b?c=d&e=f
href      https://www.example.com:777/a/b?c=d&e=f#g

And another:

var url = "http://example.com/";
var parsedUrl = require('url').parse(url);
...
protocol http:
auth     null
host     example.com
port     null
hostname example.com
hash     null
search   null
query    null
pathname /
path     /
href     http://example.com/
