I still have my reading list from when I started out with React. Here are some of the most valuable resources that helped me grok React: http://krasimirtsonev.com/blog/article/react-js-in-design-pa... http://chibicode.com/react-js-introduction-for-people-who-kn... https://medium.freecodecamp.com/the-5-things-you-need-to-kno... https://www.fullstackreact.com/30-days-of-react/
