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

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?

Answer 1

Its simply shorthand for:

$(document).ready(function(){

});
