The right way to remove a class with jQuery

I have a simple question that interests me a lot: If I want to remove a CSS class with jQuery, what's the right way? 1. removing after checking for the existence of the class?

if($(div).hasClass('css-class')) {
  $(div).removeClass('css-class');
}

2. just removing it?

$(div).removeClass('css-class');

3.any other suggestions?

For removing class using jquery I prefer the 1st option for checking existence of class for a specific dom element and then remove the class applied for that DOM element eventhough jquery does not throw any error even if that DOM element has not been applied that class

E.g. 

 if($(div).hasClass('css-class')) {
   $(div).removeClass('css-class');
 }

Just remove it. It's not like jQuery's going to throw an error (or anything like that) if the element does not have the class you're removing.

$(div).removeClass('css-class');
