GUI Tool to test javascript
<p>I am looking for <strong>GUI/Windows based</strong> tool to test my javascript code there instead of using firebug or other in-browser tool. </p>

<p>I want to play around with javascript language outside of the browser to learn more about it.</p>

<p>Has anyone come across such tool? I could not find one :(</p>

<p><strong>Edit:</strong> I am looking for GUI/Windows based on which can be used even if I am not connected to <strong>internet</strong> and still play around with javascript.</p>
