title: How do I add one single value to a JSON array?
body: <p>I am kind of new to the world of interface, and i found JSON is amazing, so simple and easy to use. 
  But using JS to handle it is pain !, there is no simple and direct way to push a value, check if it exists, search, .... nothing !</p>
  
  <p>and i cannot simply add a one single value to the json array, i have this :</p>
  
  <pre><code>loadedRecords = {}
  </code></pre>
  
  <p>i want to do this :</p>
  
  <pre><code>loadedRecords.push('654654')
  loadedRecords.push('11')
  loadedRecords.push('3333')
  </code></pre>
  
  <p>Why this is so hard ???!!!</p>
