Hi,

i noticed that there are two ways to define functions:

```php
function hello () {
// do something
} 

```

```php
hello = function () {
// do something
}

```

which one should i use? or does it not really matter.

nope, it doesn’t matter 🙂

although i usually define them like this:

```auto
var hello:Function = function () {
trace("hello everybody!");
};

```

If you’re bored, you can check out the help file or livedocs - it recommends the  
[AS]function myFunc(arg:Type):ReturnType{  
//…  
}[/AS]  
syntax inside of class files…

function hello(){} can be called before its definition in the script.

hello = function(){} can be created in the scope of another object.
