title: Does async programming mean multi-threading?
body: <p>lets talk about JavaScript code which has <code>setInterval</code> methods every <code>2</code> sec.</p>
  <p>I also have a <code>onblur</code> animation event for some control.</p>
  <p>In a case where <code>onblur</code> occurs (+ animation), I might get the <code>setInterval</code> function.</p>
  <p><strong>Question</strong>:<br />
  Does async programming mean multi-threading? (in any way?)</p>
