How to get Url params after slash

Question

I have a URL "https://www.example.com/username" and I want to extract the username from the URL. For example 'https://www.facebook.com/david'

[`window.location.pathname`](https://developer.mozilla.org/en-US/docs/Web/API/HTMLHyperlinkElementUtils/pathname) — Elan Hamburger, Apr 13 '19 at 03:07
how is `https://www.facebook.com/david` extracted from `https://www.example.com/username`? — Jaromanda X, Apr 13 '19 at 03:09
This should have been very easy to research enough yourself to at least come up with a starting point .

 let href = "https://www.facebook.com/david"; 
// let href = "https://www.facebook.com/david"; // Current window url; 

// Creating URL object
let url = new URL(href);

console.log(url.pathname.substring(1));  // David

// If you looking for parameters after ? 
let exampleUrl = "https://www.facebook.com?name=david";
let paramUrl = new URL(exampleUrl);

console.log(paramUrl.searchParams.get("name"));   // david or null if not exist

In node.js, you should use the url module.

const Url = require('url');
console.log(new Url('https://www.facebook.com/david').pathname);
// 'david'

You can use URL API and if you want to get rid of leading / you can use substring after taking the pathname from url

let url = `https://www.example.com/username`
let url2 = `https://www.example.com/username/somevalue`

let parsed = (url)=> {
   let urlParsed = new URL(url)
   return urlParsed.pathname.substring(1)
}

console.log(parsed(url))
console.log(parsed(url2))
