/* example of a for loop

This example uses very common syntax for a count-controlled loop. The counter i goes from 0 to n-1, running the loop n times. Sometimes it's useful to know that after the looop i equals n.

var n = 3;
for (var i = 0; i < n; i = i + 1) {
    // useful code would go here
    alert("i = " + i);
}
alert("after loop, i = " + i);
