As a fellow old-schooler who's been getting back into JS myself, I've come across a couple of these types of resources that I found particlarly helpful. Here's the links:

- "Modern JavaScript Explained for Dinosaurs," by Peter Jang: https://medium.com/the-node-js-collection/modern-javascript-...

- "Modern JavaScript for Ancient Web Developers," by Gina Trapani: https://postlight.com/trackchanges/modern-javascript-for-anc...

(Don't let the "ancient"/"dinosaur" stuff scare you off -- they kid because they love.)

Hope this helps!
