Is there any effective difference between the get operator and defineProperty?
<p>Is there any real difference between the <a href="https://developer.mozilla.org/en/JavaScript/Reference/Operators/Special/get"><code>get</code></a> operator:</p>

<pre><code>var obj = {
    get prop () {
        //insert code here
    }
};
</code></pre>

<p>and using <a href="https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Object/defineProperty"><code>defineProperty</code></a>:</p>

<pre><code>var obj;
Object.defineProperty(obj, "prop", {
    get: function () {
        //insert code here
    }
}
</code></pre>

<p>The MDN pages say that compatibility is about the same.</p>
