Question about JavaScript syntax
<p>What kind of JavaScript is this <code>Page.getProximityListCallback = function(obj) {</code>; is this a function? </p>

<p>Surely it is but what is it with this syntax? Can someone explain?</p>

<p><strong>Update</strong>:
Thank you for your answers. Here is a follow up: Why then use <code>function Page() {}</code>? What is its purpose? Why not just call getProximityListCallback()?</p>
