title: Spread syntax doesn't work to destructive an array
body: <p>I am new to Javascript and is confused why the following won't work? </p>
  
  <pre><code>var array = [1, 2, 3, 4]
  var spread = ...array;
  </code></pre>
  
  <p>I was expecting it would become <code>1, 2, 3, 4</code>. Instead, it gave an error message <code>Unexpected token ...</code>. Can anyone explain this to me?  </p>
  
  <p>Thank you so much!</p>
