Can outside developers access closure variables during runtime?
<p>Essentially I want to store a variable in the client that I don't want people viewing or changing.</p>

<p>In the following code example:</p>

<pre><code>(function () {
    var foo = 'bar';
})();
</code></pre>

<p>Can anybody use tools or the browser to access and/or (more importantly) change the value of foo? Links to more information or tools that might do this would be appreciated. I'll be researching more in the mean time.</p>

<p>Thanks in advance</p>
