Help with array

[magicgavin]

i have the following code:

var my_deck=new Array(1,2,3,4,5);
var area_deck=new Array();
function ShuffleDeck(){
area_deck=my_deck;
area_deck[0]="a";
alert(my_deck)
}
ShuffleDeck()

The part that I don't understand is that when the alert pops up it shows...

a,2,3,4,5

Why is this happening and how can I fix it. I don't see how the "a" ends up in the my_deck array when i made the change to the area_deck.

Its in the sequence of your statements.

So how do I fix it so this does not happen?

var my_deck=new Array(1,2,3,4,5);
var area_deck=new Array();
function ShuffleDeck(){
arena_deck=my_deck.slice(0,my_deck.length);
area_deck[0]="a";
alert(my_deck)
}
ShuffleDeck()

Thanks for your help!
