Any existing tool for JavaScript execution context Visualizations?
<p>I'm wondering whether there is already exists such tool doing:</p>

<ol>
<li>parse JS code (not expecting big block)</li>
<li>visualize execution context / scope chain, and even prototype chain.</li>
</ol>

<p>The motivation is simply because JS execution context, scope chain is usually confusing, especially for non-advanced guys. Visualization could make thing to be better understood.</p>

<p>Otherwise, could you have some suggestions regarding building up from scratch.</p>

<p>Thanks a lot.</p>
