Named Self Invoking Function

I use this pattern for polling data from servers periodically. This makes the code less clutter (especially setTimeout line).

(function poll() {
  $.get("/somedata", function (data) {
    // Processing data...
    setTimeout(poll, 1000);
  });
})();

If you needed a recursive self-invoking function then it may make sense:

(function loop(i) {
    console.log(i);
    i++;
    if(i < 10) {
        loop(i);
    }
})(0);
