I feel great when I replace jQuery with JavaScript... What about you?

That moment you convert jQuery to JavaScript... I feel super charged and awesome! 🤓 😎

My latest conversion:

jQuery

$(elem).addClass('anim-elem');

JavaScript 

if (elem.classList)
  elem.classList.add('anim-elem');
else
  elem.className += ' anim-elem';

What was your last jQuery to JavaScript?
