Replacing jQuery with these methods seems like a great opportunity for learners to improve their understanding of javascript. Also, with ES6 javascript, there seems to be less need for jQuery.
I think this is a good point of view on the topic, and personally resonates with me. I ditched jQuery at the same time I read “JavaScript: The Good Parts” and after that I realized I was never conceptually building systems, only little puddles of functionality, when I used jQuery for FED.
