title: I'm confused with this (javascript)
body: <p>I was messing around with javascript as I am new to it and seeing how it worked.</p>
  
  <p>why does this:</p>
  
  <pre><code>for(x=20;x&gt;=1;x--){
  document.write(x + x-- +", ");
  }
  </code></pre>
  
  <p>write out the 4 times table backwards</p>
  
  <p>I'm confused... :(</p>
