title: How do I remove associative array from javascript?
body: <p>I found the way to delete an item of associative array by :</p>
  
  <pre><code>delete array['knownkey'];
  </code></pre>
  
  <p>but what about delete the whole associative array,I mean just like empty an normal array:</p>
  
  <p>the way to empty an normal array is [I found on the google]: </p>
  
  <pre><code>array = []  //or
  array.length = 0 
  </code></pre>
  
  <p>So,the associative array has the way to empty or remove the all items at once ....</p>
