How does var work? Quick question

Hello guys,

I have a .js file resembling something like

[code]
var currentaddress=””;

function getURL(username)
{
if(username==”john”)
{ currentaddress = “www.google.com”;}
else
{ currentaddress = “www.yahoo.com”;}
}
[/code]

My question is, assuming that 100 users are running this .js file, each user will have their own copy of currentaddress, is this correct? I won’t have just one copy which keeps changing depending on who was the username the last time it was called.

Thanks much.
