Static variables in JavaScript

Question

How can I create static variables in Javascript?

Answer 1

In JavaScript variables are static by default. Example:

var x = 0;

function draw() {
    alert(x); //
    x+=1;
}

setInterval(draw, 1000);

The value of x is incremented by 1 every 1000 milliseconds
It will print 1,2,3 so forth
