Jquery elements declared as variables

Question

I would like to know best practices when declaring jquery dom elements as variables. Any difference between

var div = $('div'); 

and

 var $div = $('div'); 

besides better readability? Thanks

Answer 1

$div simply instructs the code reader that it represents a jQuery object. No, there is no difference.

Answer 2

It makes no difference, it will only indicate its jQuery object. This usually follows the convention.
