It is possible to do that without the variable assignment in JS...

    [].forEach.call(document.querySelectorAll('div'), function(el) {
        el.classList.add('new');
    });

But I don't disagree that the jQuery example is easier to write/read/remember.

Though with frameworks like Angular or React I'm beginning to question whether we should ever be writing code like this at all.

Agreed. I mainly use React these days, and directly modifying the DOM is starting to feel dirty.
