title: Fetch APIs - Is it blocking or non-blocking code?
body: <p>I've been looking at the <code>Fetch API</code> for a couple of days now. </p>
  
  <p>While learning I came across the statement <strong>"using <code>fetch()</code> doesn't block your DOM "</strong> as it uses promises.</p>
  
  <p>Happily moving forward with these tutorials and checking out some new ones, I saw a guy stating <strong>"using <code>fetch()</code> does block your DOM"</strong> in a presentation.</p>
  
  <p>Can anyone educate me which one of the two it is? </p>
