Question

I have a piece of code looking like so:

$(function() {
  // some code here to do stuff
})();

Any ideas what the extra () at the end contribute to? With or without them the script works fine.

I’m sure this has been discussed before but I don’t know of a way to code-search SO.

I would say it’s a typo.

Either (JQuery DOM Ready):

$(function() {
  // some code here to do stuff
});

Or (Self-invoking anonymous function):

(function() {
  // some code here to do stuff
})();
