AS3 - Children adding reverse

Today I learned an extra feature of adding children into a DisplayObject in reverse.
Normally I would make two loops. First one is adding the children, the second is placing the children in reverse.
But... it can be done so much easier:

for(var i:int = 0; i < numChildren; i++)
{

    container.addChildAt(child,0);

}

The second parameter sets the child on the first place.

For many known, not for me.. maybe not for you either....

getNextHighestDepth in as3

In as2 you were able to put a movieclip on top of all the other containing movieclips. I'm working with as3 now and was searching for this same option.

You can do it with one line of code:

as2:

//container is the parent of the movieclip
movieclip.swapDepths(container.getNextHighestDepth());

as3:

//container is the parent of the movieclip
container.setChildIndex(movieclip, (container.numChildren - 1));
