JQuery - What is the purpose of this syntax $(function () { ... });

Question

I'm working with SignalR, and by extension, JQuery.

Some initialisation code runs inside a function block defined with the following syntax:

$(function () { 

    // ... Init code here e.g. 

    var hub = $.connection.myHub;
});

What is the functional difference here compared with just executing scripts directly within a pair of script tags?

I know it still has to run within script tags, I mean the line of code within the function definition. — gb2d, Mar 19 '13 at 14:39

Its simply shorthand for:

$(document).ready(function(){

});

$(function () is equivalent to document on ready. The function will execute everything inside the {} tags once the DOM has loaded.

An alternative way is:

$(document).ready(function() {

});
