This is a recommendation of a JS tutorial for beginners by Dan Abramov. It's called Just JS and I liked it very much, especially for the visualisations by Maggie Appleton. The cover image of this article is one of hers.
Unfortunately the tutorial is only available by mail and it's very shot, 9 courses only. But I can assure you: it's worth it. The mental model for how the inners of JS work are pure gold. You can subscribe here on Dan's website for Just JS.
P.S.: Dan Abramov is working on React and the (co-) creator of Redux and create-react-app.
