title: How to add a property at the beginning of an object in javascript
body: <p>I have</p>
  
  <pre><code>var obj = {'b': 2, 'c': 3};
  </code></pre>
  
  <p>And i would like to add a property at the beginning (not at the end) of that object:</p>
  
  <pre><code>var obj = {'a': 1, 'b': 2, 'c': 3};
  </code></pre>
  
  <p>Is there a clean way to do that?</p>
