Is it useful to use requestanimationframe when javascript updates a class?

Context



I learnt that when I want to keep fluidity on my UI, instead of:



document.querySelector('#div').style.width = '100px';


I can use:



requestAnimationFrame(function() {

  document.querySelector('#div').style.width = '100px';

});


Question



Is it useful to do the same thing for a class change? I mean is this:



document.querySelector('#div').classList.add('big');


useful to keep a good UI fluidity?



Note



I also learnt, with the video of Jake about the Javascript event loop, that CSS is applied on a different thread than Javascript, hence my question because since it is Javascript sending the class change, does it is counted as part of the JS event loop or the CSS event lopp?
