title: Declare multiple variables in JavaScript
body: <p>I want to declare multiple variables in a function:</p>
  
  <pre><code>function foo() {
      var src_arr     = new Array();
      var caption_arr = new Array();
      var fav_arr     = new Array();
      var hidden_arr  = new Array();
  }
  </code></pre>
  
  <p>Is this the correct way to do this?</p>
  
  <pre><code>var src_arr = caption_arr = fav_arr = hidden_arr = new Array();
  </code></pre>
