title: How to get the first string from the URL?
body: <p>I'm a newbie in web development so pls forgive my newbie question.</p>
  
  <p>I have a URL "<a href="https://123asd.my.website.com/blabla/blabla/blabla" rel="nofollow noreferrer">https://123asd.my.website.com/blabla/blabla/blabla</a></p>
  
  <p>What I'm trying to figure out is how do I get the "123asd" so that I can set in on my var. Thank you</p>
