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

var div = $('div');

and

var $div = $('div');

besides better readability? Thanks

$div simply gives an indication to the reader of the code that it represents a jQuery object. So no, there is no difference besides that.

There is no difference it will only indicate its a jQuery object. It is generally followed as a convention.
