title: JavaScript curly braces with no function or json
body: <p>Just opened a client's javascript file and the first lines are along the lines of this:</p>
  
  <pre><code>{
      var s_account="blog";
  }
  </code></pre>
  
  <p>Which I don't get.  Normally, in my experience, curly braces wrap around a function... </p>
  
  <pre><code>function welcome(){ ...
  </code></pre>
  
  <p>...or a <del>json</del> <em>JavaScript</em> object</p>
  
  <pre><code>var attributes = { this : "that...
  </code></pre>
  
  <p>Can anyone tell me why there are curly braces with no text before them or after them? What does it do / what is the point of it?</p>
