title: Split multiple words started with @ sign
body: <pre><code>var test = "Hello all, this is a message and i want to mention @john, @smith and @jane...";
  </code></pre>
  
  <p>And what i want to get is:</p>
  
  <pre><code>var result = ["john", "smith", "jane"];
  </code></pre>
  
  <p>i can take the last username in the string but not all of them. I am OK with regexp or other string functions.</p>
  
  <p>Thank you.</p>
