Just to addon to what Waseem here has said:

When you are using the default jQuery library, the variable $ is set to the value of jQuery, which creates a shortcut for you so that you don't have to keep typing jQuery everytime you want to access it, you can just type $.

[jQuery] Re: var $varname

its not really a jquery variable

in standard js you can say
var $myvar = "hello";
and
var myvar = "hello";

both will work the same

you can access jquery using either the $ or JQuery
like

$("#myid").hide();
JQuery("#myid").hide();

in a line of the JQuery library code you would see something like

JQuery = window.JQuery = window.$ ...

your could say its like short hand code

instead of saying JQuery("") al the time you can just say $("")

what's the difference between:

obviously I think 2nd is a jQuery variable? If that's the case why
should I care and where is the docs on that?
