title: i'm new to coding. i need a quick explanation
body: <pre><code>var x = 3;
  var y = x++;
  </code></pre>
  
  <p>Can someone tell me why <code>var y = 3</code> and <code>x++ = 4</code>.</p>
  
  <p>I assumed <code>x++ = 4</code> therefore <code>y = 4</code> but it's not.</p>
  
  <p>This dummy needs help understanding why <code>y is not 4</code> but <code>3</code></p>
