title: What is the difference between return and return()?
body: <pre><code>function a() { return 1; }
  function b() { return(1); }
  </code></pre>
  
  <p>I tested the above code in Chrome's console, and both returned <code>1</code>.</p>
  
  <pre><code>function c() { return "1"; }
  function d() { return("1"); }
  </code></pre>
  
  <p>I also tested the code above, and both of the functions returned <code>"1"</code>.</p>
  
  <p>So what is the difference between using <code>return</code> and <code>return()</code>?</p>
