<pre><code>(function() 
 {
     //codehere
 }
)();
</code></pre>

<p>What is special about this kind of syntax?
What does ()(); imply?</p>

The creates an anonymous function, closure and all, and the final () tells it to execute itself.
It is basically the same as:
```
```
function name (){...}
name();
```
```
So basically there is nothing special about this code, it just a 'shortcut' to creating a method and invoking it without having to name it.
This also implies that the function is a one off, or an internal function on an object, and is most useful when you need to the features of a closure.
