change base function behaveiour
<p>Assume I have executed this js code:</p>

<pre><code>var container=function() {
    //do something
}

container.a=function {
    //do something 2
}

container.b='34'
</code></pre>

<p>Here, in order to change container.a function for example I need to do:</p>

<pre><code>container.a=function() {
    //do something 3
}
</code></pre>

<p>How do I change the function container() ?</p>
