title: Javascript - remove an array item by value
body: <p>My situation:</p>
  
  <pre><code>var id_tag = [1,2,3,78,5,6,7,8,47,34,90];
  </code></pre>
  
  <p>I would like to <em><code>delete where id_tag = 90</code></em> and to return:</p>
  
  <pre><code>var id_tag = [1,2,3,78,5,6,7,8,47,34];
  </code></pre>
  
  <p>How can I do that?</p>
