Object literals in javascript. How to access quoted "prop s" of object?
<p>In javascript tutorial I've see the next object definition:</p>

<pre><code>var myObject = {
    validIdentifier: 123,
    'some string': 456,
    99999: 789
};
</code></pre>

<p>What the purpose of such key-value pairs with quoted ones as keys? How one could operate with such values?</p>
