title: Javascript variable object keys
body: <p>I am attempting to add a variable key, with no luck.</p>
  
  <p>Here's what I got so far:</p>
  
  <pre><code>mysql('translations',{
      check: 'element_id',
      element_id: element_id,
      {'lang-'+lang_id}: value
  });
  </code></pre>
  
  <p>The variable key is the last line of the function.</p>
  
  <p>Any ideas?  </p>
