Books (or rather, eBooks, really) are how I learned about programming to begin with. So I'd say I prefer them to an extent, but if you really desire interactability, online sites are definitely the way to go. I tend to retain more gleaning from a book.

Thanks for the article recommendation, I'm not really familiar with Vue yet but I'm hoping to learn about it as well. Hopefully I will be able to approach it more after reading this article. Thanks again!
