None of them is valid syntactically. – Tibos Nov 07 '13 at 15:35 — Tibos, Nov 07 '13 at 15:35

Take a look at the API docs here: http://api.jquery.com/jQuery/#jQuery3

$(function(){}) and jQuery(function(){}) are, for most practical purposes, the same thing. $ is a kind of an "alias" for jQuery. Whenever you pass a function as the first argument into $() or jQuery(), it will call that function when the DOM is ready.

I think this would be best explained by Paul Irish in the 10 Things I Learnt From JQuery Source video he made.

He not only covers your question, but various other points - well worth a watch!!

It's pretty much like the document.onload: the script will be executed when everything has been load.
It's very useful when you do some DOM manipulation.

Not specifically true - document.onload and document.onready are slightly different... http://stackoverflow.com/questions/3698200/window-onload-vs-document-ready – Stuart.Sklinar Nov 08 '13 at 10:32
