[osflash] Array with Unique Value

[Darren Cook]

> I'm looking for a way to create an array with only unique values.

I usually use a hash table (aka. an actionscript object); the values can
just be "true". E.g.

obj={};
for(var ix=0;ix<myArr.length;++ix)obj[myArr[ix]]=true;

Then if you needed the data back in the array you could do:
myArr=[];
for(var key in obj)myArr[]=key;

Maybe that's inefficient, and there is a better way?
