title: Javascript split remove ":" colon character
body: <p>I have a string like this.</p>
  
  <pre><code>var a="1:2:3:";
  </code></pre>
  
  <p>I want to split it with <code>a.split(":")</code> to remove the ":" colon character.</p>
  
  <p>I want to get this as the result:</p>
  
  <pre><code>["1","2","3"]
  </code></pre>
  
  <p>But instead the result of <code>a.split(":")</code> is this:</p>
  
  <pre><code>["1","2","3",""]
  </code></pre>
