<script type="text/javascript">
// Define a variable to be accessed within the
// self-executing function block.
var counter = 0;
// Create a self-executing function block; however, rather
// than passing in an anonymous, headless function, let's
// pass in a named function.
(function useCounter(){
// Increment and log counter.
console.log( ++counter );
// Call *this* function again in after a short timeout.
// Since it has a name, we don't have to use the
// depracated arguments.callee property.
setTimeout( useCounter, 1000 );
