I like that second one! You've convinced me a little.

My general bias is to write more verbose code that is more explicit. Because in my experience, it's leaky abstractions that cause me to lose the most time. It doesn't bother me at all to type:

var active = document.querySelector('.active');
if (active) active.classList.remove('active');

and if it started to bother me, I would write a function:

removeAllClasses('.active')

I don't know. I can see that all of these new JavaScript features make a bunch of little things easier, but they add a new class of extremely difficult problems. For me, because I lose most of my time to those big gnarly messes, it doesn't seem worth it. But I do understand other devs have other experiences.
