JavaScript Variable Scope

Dflying | 10 March, 2006 17:39

In JavaScript, there's a 'wired' feature that the variable scope is only the function. For example, in the following code:

var i = 1;
{
    var i = 2;
}
alert(i);

You will get 2 alerted. That's really interesting and everyone should pay more attention to.
