Is it possible to add dynamically named properties to JavaScript object?
<p>In JavaScript, I've created an object like so:</p>

<pre><code>var data = {
    'PropertyA': 1,
    'PropertyB': 2,
    'PropertyC': 3
};
</code></pre>

<p>Is it possible to add further properties to this object after it's initial creation if the properties name is not determined until run time? i.e.</p>

<pre><code>var propName = 'Property' + someUserInput
//imagine someUserInput was 'Z', how can I now add a 'PropertyZ' property to 
//my object?
</code></pre>

<p>Thanks</p>
